Research and Simulation of Fuzzy PID Controller

Abstract:

In light of the difficulty for the multi-variable fuzzy controller to formulate a sophisticated set of rules concerning multi-dimensional controlling, this project proposes a parallel connection fuzzy PID controller, each PID employing two fuzzy controllers to carry out parameter tuning. This project applies the parallel connection PID fuzzy controller in controlling the jacking system of the multi-hydraulic cylinders. Through the AMESim/Simulink connector, joint simulation is achieved for the hydraulic system and the controlling system. The result of the simulation reveals that this application effectively improves the dynamic and static performance of the system, as well as synchronization precision in the jacking of the hydraulic cylinders.
