초록
In this study, for the control of a single water tank system, a fuzzy-PID controller design techniquebased on a fuzzy model is investigated. For this purpose, a water tank system is linearized as a number ofsubmodels depending on the operating point, and a fuzzy model is obtained by fuzzy combining. Each submodelis approximated as a first order time delay model, and a PID controller is designed using several existingtuning techniques. Then, through the fuzzy combination of this controller using the same method as thatof the fuzzy model, a fuzzy-PID controller is designed. For the proposed technique, a simulation is performedusing the fuzzy model of a water tank system, and the validity is examined by comparing its performancewith that of a PID controller.
