Abstract

This paper presents a H-infinity synthesis with pole clustering based on LMI region schemes for liquid slosh control. Using LMI approach, the regional pole placement known as LMI region combined with design objective in H-infinity controller guarantee a fast input tracking capability and very minimal liquid slosh. A graphical profile of the transient response of liquid slosh suppression system with respect to pole placement is very useful in giving more flexibility to the researcher in choosing a specific LMI region. With the purpose to confirm the design of control scheme, a liquid slosh model is considered to represent the lateral slosh movement. Supremacy of the proposed approach is shown by comparing the results with hybrid model-free fuzzy-PID controller with derivative filter. The performance of the control schemes is examined in terms of time response specifications of lateral tank tracking capability and level of liquid slosh reduction.

Abstract

This paper is under in-depth investigation due to suspicion of possible plagiarism on a high similarity indexThe development of hybrid renewable energy sources is vital in power generation. This study focused on design of fuzzy logic control on hybrid PV/Wind system in order to improve the speed of DC motor. The fuzzy logic control based on battery management system has been designed for effective power utilization and improvement of the DC motor speed performance. In battery management system, a control was proposed to operate the charging and discharging mode of battery during non-linear power generation. While the battery would charge whenever the renewable energy power was greater than consumer load power, the battery would discharge whenever the renewable energy power was less than the consumer load power. DC motor speed control, included the simulation, implementation of fuzzy logic controller to DC motor and comparison between PID controller and Fuzzy Logic Controller. The proposed model was simulated using Matlab environment and the results was analyzed. Finally, simulation results were evaluated and validated to determine the effectiveness of the proposed controller.

Abstract

Vision system applied in electrical power generated mobile robot to provide a comfortable ride while providing comfort to tourist to interact with visitors. The camera is placed in front of the mobile robot to snap the images along in pathways. The system can recognized the sign which are right, left and up by using Harris corner algorithms and will be display in Graphical User Interface (GUI). A sign can be determined from the vertex coordinates according to the degree to distinguish the direction of the sign. The system will be tested in term of percentage of success in Harris point detection and availability to detect sign with different range. The result show the even though not all Harris point in an image can be detected but most of the images possible to recognise it sign direction.

Abstract

This project is describes the development of underwater vehicle which is remotely operated crawler (ROC). The ROC is developed for the implementation of underwater surface floor and used as for rescuing application. This project is aim to reduce the risk the human life and to solve the disability of human to dive to the underwater for rescue and archeologist work in a longer period. Due to the underwater vehicle that can be operated in a larger depth and reducing the liability of the human life. Moreover, the main problem with this ROC application is to travelling under the uneven of the underwater floor and make sure it always have negative buoyant and a good stability to perform at uneven surface of underwater. Furthermore, the ROC need the overcome the obstacle of the underwater surface without any problem. Therefore, the design of ROC is based on four wheel mechanism to maneuver it at the uneven surface. Besides that, the ROC is tethered and control manually by using a joystick controller and the Peripheral Interface Controller (PIC) are used to control this ROC. This method is to fulfill the target of the project that are to develop and fabricate the ROC and to study the performance of the ROC in terms of controllability, stability and maneuverability. As a result, the movement of ROC is analyzing in order to gain the requirement of stability and the buoyancy in the water. Moreover, the development of the ROC can be tested in several experiments which includes overcome obstacle, controllability, and it performances to be operated on the surface floor of underwater. Hence, this project will gives the good impact and benefit related to the underwater industries and can be applied in the rescuing application in the future.

Abstract

This paper introduced to develop and implementation of PC based controller for humanoid robot using digital potentiometer. The main objective in this paper is to develop and implement the joystick controller by using a digital potentiometer circuit board that be able to control the humanoid robot movement. The Arduino board and digital potentiometer will be integrated by connecting both pins in between wiper, W pin and ground, GND to the DB9 pins of remote control platform, which is TX and RX pins respectively. Humanoid robot as known as TOMY i-SOBOT is used as a preferred model due to wide usage in many applications. A digital potentiometer will be transmitted the voltage and current value depend on the digital level through serial communication to give the instruction for humanoid robot movement. The humanoid movement based on Guided User Interface (GUI) where the user give a commands by pressing the button on the GUI such as turn left, right, forward, and reverse. The results show that the humanoid movement able to control based on the voltage and current in a digital potentiometers value.

Abstract

Precision and robustness are essential for any automation actuator. Due to the nonlinear characteristics of the pneumatic actuator, advanced nonlinear control algorithms provide exceptionally precise control but are sensitive to disturbances. Owing to this factor, an adaptive element is embedded into the control structure to obtain a robust strategy by integrating single input fuzzy logic (SIFL) with the nonlinear hyperbolic PID controller (T NPID). SIFL characterizes a variable rate in the function while reducing computational complexity against an equivalent classical fuzzy logic (FL) by up to 36.5%. The signed distance SIFL selection is also a novel structure that has never been applied in the pneumatics control field. The robustness of the controller is analysed via dynamic stiffness and validated by applying multiple load disturbances. The improvement gained for the T NPID+SIFL’s transient rise time and multi-step IAE index under no load disturbance is 71.381% and 68.854%, respectively, compared with a classical sliding mode controller (SMC). Under a maximum 9 kg load disturbance (limited within the scope of this research), the T NPID+SIFL’s IAE index performance obtained an improvement of 68.638%. When compared with a baseline nonlinear hyperbolic PID (NH PID) strategy under no load disturbance, the steady state error and overshoot also improved by 74.797% and 15.385%, respectively. The results show outstanding performance compared with a robust controller as well as a similar baseline nonlinear PID control. Asymptotic stability analysis, such as the asymptotic tracking region (ATR), will be able to consolidate the trajectory tracking performance together with the experimental validation of a smooth trajectory, simulating a real-time robotic actuator under movement control.
