This paper presents a fuzzy PID controller with on-line multi-linear interpolation. The method of designing the controller is showed. Based on the model of fuzzy number, the multi-linear is adopted replacing the fuzzy inference. The stable performance of the controller is thus improved, and the stable oscillation caused by the scaling errors is essentially eliminated. The simulation result demonstrates the validity of the proposed algorithms.
