Parameter adjusting fuzzy control of multi-variable coupling system

Based on analysis of influences of fuzzy control and PI method on control systems, a parameter adjusting fuzzy PI method for multi-variable coupling systems is presented. Two independent fuzzy controllers are used to identify proportional coefficient incremental_ΔKp and integral coefficient incremental _ΔKi, which achieves good results of dynamic performance. Each controller is designed independently, which makes the controller design job easier. Finally, the proposed method is used in the simulation of practical industrial plants. Simulation results show that this method has better controlling effects and the superior adaptive abilities and tracking performance.
