Abstract

Nowadays, the application that use of Electro Hydraulic Actuator (EHA) system in the industrial sector has been widely applied. This is because the system produces high power to weight ratio, smaller size, and faster responds than existing CHA (Conventional Hydraulic Actuator) system. The EHA system has been developed to replace the CHA system that has some problem such as leakage of the working fluid, maintenance load, heavy weight and limited installation space. However, the system of EHA system has produced nonlinearities and uncertainty characteristic. Therefore, to improve the performance, the parameter require to compensate the changes in EHA system. In this project, PID and LQR control tuning using PSO (Particle Swarm Optimization) by using Matlab coding. Other than that, the transient of performance in term of settling time, rise time and overshoot will be determine by compare both controllers. The performance index, integral of time square error (ITSE) will be used in optimization technique in order to find suitable parameter for PID and LQR. The last chapter, will be discussed which controllers will gives are better performance between PID and LQR with more precision and flexibility.
