Design and implementation double input fuzzy PI and fuzzy gain scheduling PI controller on hydraulic plant

摘要

Hydraulic systems are important in industry and different methods have been proposed to control them. The hydraulic system is one of systems that its model changes gradually. In this article, two different types of fuzzy PI controllers (double input fuzzy PI and fuzzy gain scheduling controller) are designed and implemented on hydraulic plant that they are Independent from model of system. Double input fuzzy PI controller is designed for setting motor slowly in working point without overshoot and fuzzy gain scheduling PI controller is designed for maximum response rate of system. Finally their responses are compared with response of classic PID controllers.
