Abstract:
To improv e the contro l accuracy o f fuzzy contro ller, the paper proposes a k ind of hybrid param eter se l-f tuning fuzzy PID contro ller in com bina tion w ith the advantag es o f conventional PID contro ller and fuzzy contro ller. The contro ller consists o f three parts: the conventiona l PID contro ller, the ga in- tun ing fuzzy contro ller and the d irec t-action fuzzy contro ller, and can adjust the contro ller param eters w ith the variation o f controlled objects. The func tions and param eters se lection o f every part in the hybr id contro ller are descr ibed in deta i.l The s imu lation experim ent on the contro l o f hydraulic system show s that the hybr id fuzzy PID contro lme thod is effective, and the contrastive results w ith conv entiona l PID contro lle r shows that the contro l a lgo rithm can improve the response and the robustness of contro lled sy stem.
