Abstract

In order to improve the speed and accuracy of the trajectory tracking control for 3R plane robot, a PD iterative self-learning control algorithm is proposed based on the PD iterative control algorithm. The error of target value and the actual value of this iteration is introduced into the PD learning gain to make the PD learning gain becomes a function of the error and to achieve the effect of self-learning. Simulation analysis of planar 3-link robot trajectory control shows that the proposed algorithm is better than unmodified in speed ability and accuracy. DOI: http://dx.doi.org/10.11591/telkomnika.v11i10.3427

Abstract

The complicated products design is a process of conflict resolution and integration decision for collaborative optimization involved in multiple disciplines including mechanical engineering, electronical engineering and control engineering, etc. It’s also a multi-disciplinary field of complex knowledge fusion process. The architecture of the product design knowledge is given by the description of the forms of knowledge in complex product design. The representation mechanism for multidisciplinary knowledge based on ontology and formal definition of the design knowledge ontology are put forward by using the theories and methods of ontology and semantic network. Finally, the multiple disciplines design knowledge expression strategy is proposed based on the above analysis and conclusions. This paper provides a new method and means for complicated product design knowledge representation involving the integration of multidisciplinary knowledge. DOI: http://dx.doi.org/10.11591/telkomnika.v11i10.3467

Abstract

Road section data packet is very necessary for the estimation and prediction in short-time traffic condition. However, previous researches on this problem are lack of quantitative analysis. A section correlation analyzing method with traffic flow microwave data is proposed for this problem. It is based on the metric multidimensional scaling theory. With a dissimilarity matrix, scalar product matrix can be calculated. Subsequently, a reconstructing matrix of section traffic flow could be got with principal components factor analysis, which could display section groups in low dimension. It is verified that the new method is reliable and effective. After that, Auto Regressive Moving Average (A RMA) model is used for forecasting traffic flow and lane occupancy. Finally, a simulated example has shown that the technique is effective and exact. The theoretical analysis indicates that the forecasting model and algorithms have a broad prospect for practical application. DOI: http://dx.doi.org/10.11591/telkomnika.v11i10.3335

Abstract

Power head is the main motive mechanism of rotary drilling rig. High axial pressure and high frequency is one of its typical working conditions. Axial loading test is a key point in power head performance tests. Overall design, system theoretical analysis and simulation of power head axial loading system were carried out. The bond graph model and state equations of power head axial servo loading system were built on the basis of bond graph theory. Hydraulic system simulation model was constructed and axial steady-state and dynamic loading simulation was made by use of hydraulic simulation software. The maximum axial steady-state load is up to 450kN and the dynamic frequency is 20Hz, both of which can meet the technical requirements. The simulation validates the feasibility of the scheme about power head axial loading system and it provides theory and practice guidance for perfecting the loading system. DOI: http://dx.doi.org/10.11591/telkomnika.v11i10.3390

Abstract

Decimal floating Point adder is one of the most frequent operations used by many financial, business and user-oriented applications but current implementations in FPGAs are very inefficient in terms of both area and latency when compared to binary floating point adder. This paper has shown an efficient implementation of a new parallel decimal floating point module on a reconfigurable platform, which is both area as well as performance optimal. The decimal floating-point Adder was further pipelined into five stages to increase the maximum frequency of operation. The synthesis results for a Stratix IV device indicate that our implementations have 25.1% reduction of the latency and 1.1% reduction of area compared to an existing alter-core adder design, presenting area and delay figures close to those of optimal binary adder trees. DOI: http://dx.doi.org/10.11591/telkomnika.v11i10.3406

Abstract

There is a few research in area of safety-critical system, therefore the study of performance analyzing method of the protocol has important practical significance for transportation engineering. This paper first briefly introduces the execution procedure of safety communication protocol, then explores the application of Petri net to establish the model of the protocol, including the process of state transition and corresponding timer which record the time, then obtains related performance data such as maintainability and failure probability, which users usually pay most attention to, with different probability of time delay and no fault in channel by simulation. Finally this paper finds that how the probability of time delay and no fault in channel could influent the maintainability and failure probability through data process with theory of probability and mathematical statistic, this could provide a certain reference for development of safety communication protocol. DOI: http://dx.doi.org/10.11591/telkomnika.v11i10.3462

Abstract

Car reverse image is transmitted by information bus. Because of the bad electromagnetic environment of the engine compartment, car’s information bus sometime will be blocked or not real-time, which can lead to the uncertainty of information transmission, and will cause the risks of security and reliability of the transmitted network. A GHM multi-wavelet is adopted by this paper to restore the interference car reverse image. After balanced processing the GHM multi-wavelet, constant module blind equalization algorithm based on balanced orthogonal multi-wavelet transform (MWTCMA) is used in this paper. Compared with the constant module blind equalization algorithm (CMA) and wavelet transform constant module blind equalization algorithm (WTCMA), results show that MWTCMA can eliminate the multi-wavelet pre-filtering process through multi-wavelet transform on input signal, and improve the convergence speed. The calculation error of MWTCMA is also smaller than the other two methods.DOI: http://dx.doi.org/10.11591/telkomnika.v11i10.2697

Abstract

With the wide application of wireless sensor network in many domains of the national economy, more and more researchers pay attentions to data management of wireless sensor network. As the main means of multi-decision and data mining, skyline query in wireless sensor network gradually becomes a focus of the researches. Resent years, skycube, an important variation of skyline query, has been deeply discussed, but due to the special properties of wireless sensor network, existing approaches could not be directly applied into the sensor environment. In this paper, skycube query in wireless sensor network is further researched and a new skycube query algorithm based on extended skyline (SCAES) is proposed in certain environment, and a new threshold skycube query algorithm based on threshold extended skyline (p-SCAES) is proposed in uncertain environment. SCAES algorithm shifts the necessary data from the network based on extended skyline and filters the data that do not belong to skycube. p-SCAES brings in the probability threshold mechanism to decrease the data transmission. Therefore, the number of data transmission in both SCAES and p-SCAES is reduced as a consequence. The experimental results show that both SCAES and p-SCAES could greatly reduce the data transmission no matter in certain or uncertain environments, while calculating the correct skycube of the network, and prolong the life span of the wireless sensor network. DOI: http://dx.doi.org/10.11591/telkomnika.v11i10.3705

Abstract

Auction models and protocols are found efficient in managing resources allocation, which are a key technology in grid computing system. In this paper, a new multi-attribute multi-round reverse auction is proposed, and related reverse auction based protocols are designed. The resource user’s satisfaction degree is introduced into the traditional grid resource allocation problem to help the grid resource broker make multi-attribute decisions with incomplete information. Numerical simulating experiments show that our model and protocols can satisfy the resource user’s quality demand on multiple attributes, and achieve high efficiency in user utility. The results also illustrate that the on-line multi-attribute algorithm in ONMRA protocol has better performance in an on-line setting for grid allocation. DOI: http://dx.doi.org/10.11591/telkomnika.v11i10.3347
