Abstract

In order to improve the precision of the tire pressure monitoring system, the Bayes method is applied to establish its mathematical model of multi-sensor information fusion. The temperature and pressure in the tire, which are the complementary information, are integrated in the model through analyzing the mechanism of tire burst generated by temperature and pressure. Through the temperature compensation of tire burst pressure threshold value, the false alarm and false negative are avoided to the hilt. The experimental results show that compared with the traditional TPMS, the accuracy of the measuring results of this model is improved and thus the system’s monitoring ability is improved so that the traffic safety is guaranteed. DOI: http://dx.doi.org/10.11591/telkomnika.v14i3.7895

Abstract

This paper deals with a comparative analysis of various converter topologies for Power Factor Correction (PFC) in switched reluctance motor drives. Hence a power factor corrected converter required for obtaining the improved PQ at the AC mains for an inverter fed SRM drive has been analyzed. The SRM when fed by a DBR with a high value of DC-link capacitor results in highly distorted supply current and a poor power factor. A new bidirectional bridgeless LUO converter is used. The bridgeless LUO converter is a mixture of two dc-dc converters with one or two semiconductor switches in the current flowing path thereby reducing the current stresses in the active and passive switches. Circuit efficiency is further improved as compared to conventional Converters. LUO converters are new series of DC/DC Converters that have very low ripple of voltage and current and have output wave with high quality, high transfer voltage gain and high power density. DOI: http://dx.doi.org/10.11591/telkomnika.v14i3.7781

Abstract

In order to improve the attitude accuracy, the thesis establishes the all-attitude integrated BDS/INS navigation nonlinear system model based on the position, velocity, attitude by adding the BDS’s attitude measurement information into the measurement equation of the traditional BDS/INS integrated navigation nonlinear system model. Considering the problem that the dynamic navigation system model is difficult to accurately describe the complex navigation environment, the thesis improves the dynamic characteristics of the information distribution of the federal filter algorithm which could timely change based on the eigenvalues ratio of each subsystem’s error variance matrix. Then, the adaptive federal unscented particle filter (AFUPF) is proposed. The simulation shows that the proposed algorithm could effectively weaken the impact on the system accuracy of the inaccurate high-dynamic model, and improve the adaptability, the fault tolerance and the accuracy, especially the attitude accuracy. DOI: http://dx.doi.org/10.11591/telkomnika.v14i3.8069

Abstract

The Switched Reluctance Motor (SRM) is getting large attention for industry application due to their simple construction, high starting capabilities, high reliability, and high efficiency and also rotor carries no windings, no slip-rings there is no brushes, it requires less maintenance. In spite of the merits, it had some demerits like acoustic noise and vibration is one of major issues in SRM. The DSP-TMS320F28335 processor were implemented due to their high performance for the control applications.In this work the Random Pulse Width Modulation (RPWM) technique is used to reduce the acoustic noise and vibration by varying random turn on and turn off angle control.The acoustic noise and vibration signals are measured using accelerometer and sound level meter in 1HP, 8/6poles of SRM drive. The experimental analysis of vibration signals are measured using Lab VIEW at different speeds and load conditions. The acoustic noise signals are measured using Sound level meter .Both the Acoustic and vibrations are analyzed experimentally for different speeds and load conditions. The experimental results show that the noise and vibration analysis and also compare the sinusoidal PWM is better than Random PWM techniques. DOI: http://dx.doi.org/10.11591/telkomnika.v14i3.7965

Abstract

This paper deals with the mitigation of electromechanical wave propagation in power systems. Different conventional controllers addressed this problem, such as the conventional PSS and the conventional fuzzy logic PSS. In this paper, the fuzzy logic PSS is assisted by auxiliary signals from the fuzzy logic PSS of the interconnected machines to augment the damping of electromechanical wave propagation and the associated oscillations. The neighboring machines speed deviation and its derivatives signals are exploited through the fuzzy logic PSS to assist the local fuzzy logic PSS. The disturbance propagation and reflection phenomena are considered in the design of the adopted strategy. The efficacy of the proposed assistance of the conventional fuzzy logic PSS are examined through different simulation results. DOI: http://dx.doi.org/10.11591/telkomnika.v14i3.7837

Abstract

A three degree of freedom (3-DOF) bench-top helicopter is a simplified aerial vehicle which is used to study the behaviors of the helicopter as well as testing multiple flight control approaches for their efficiency. Designing helicopter’s dynamic control is a challenging task due to the presence of high uncertainties and non-linear behavior. In this study, Quantitative Feedback Theory (QFT) is proposed to achieve robust control over the helicopter model. It utilizes frequency domain methodology which ensures plant’s stability by considering the feedback of the system and thus removing the effect of disturbances and reducing sensitivity of parameter’s variation. The proposed technique is tested against LQR-tuned PID controller to demonstrate its procedures as well as its performance. Simulation results obtained through MATLAB Simulink software shown us that QFT algorithm managed to reduce percentage of overshoot and settling time about 50% and 30% respectively over the classical PID controller. DOI: http://dx.doi.org/10.11591/telkomnika.v14i3.7899

Abstract

This paper proposes a four port three input-dc-dc boost converter for hybridising two photovoltaic systems and a storage medium. Three unidirectional ports are utilised to interface the converter with the two input sources and the output load. A bidirectional port interfaces the converter with the storage system. The two sources individually or simultaneously supply the load and charge the battery. The proposed technique employs only four independently controlled switches with different duty ratios. The regulated dc output can be obtained by controlling these four switches and tracking the maximum power of the two photovoltaic systems. Three different modes of operation of converter influenced by the state of battery are presented. The proposed system is validated and verified by simulation performed in MATLAB under various operating conditions. DOI: http://dx.doi.org/10.11591/telkomnika.v14i3.7854

Abstract

This paper deals with the power factor correction in BLDC motor drive with different cuk derived converter topologies and the best one is simulated for power factor correction operation. Power quality issues is the major concern in the BLDC motor drive due to recommended limits of harmonics in the supply current. Conventionally the BLDC motors are powered with the help of diode bridge rectifiers which results in highly distorted supply current and poor power factor. So modification in converter topology is the research hotspot in recent years. Alternatively bridgeless converter topologies are used in place of diode bridge rectifiers (DBR). Among the bridgeless topologies cuk derived converters suited well for power factor correction. In this paper the different cuk topologies are investigated and the best one is simulated with the help of neuro-fuzzy controller in MATLAB/Simulink platform.DOI: http://dx.doi.org/10.11591/telkomnika.v14i3.7893

Abstract

This paper presents a method to find kicking range of sepak takraw game when player kicks backthe ball to the other team. To serve, one player stands in the right semi-circle on their side of the court. Theplayer throws the ball to the server, who stands in the circle on their side of the court. The player kicks theball up and over the net then opponent player kicks back the ball. This research works considered how fuzzylogic can be applied for the sepak takraw game - for addressing uncertainty in kicking range of the ball. Wehave chosen Tsukamoto’s fuzzy reasoning scheme, because the individual rule outputs are crisp numbers,and therefore, the functional relationship between the input vector and the system output can be relativelyeasily identified. The result reveals that if player serve far, kicking range will be decreased and stable duringkicking very near through kicking very far.\\ DOI: http://dx.doi.org/10.11591/telkomnika.v14i3.7833
