Abstract

Considering the multi-variable, nonlinearity, time lag and time variation characters of Variable Refrigerant Volume (VRV) air conditioning systems, a robust and self-adaptive two-stage Fuzzy Proportional Integral Derivative (FPID) controller for temperature control in a triple evaporator VRV system is proposed and simulated. The controller combines the Fuzzy-PD controller and Fuzzy-I controller with a fuzzy switch. The fuzzy-PD controller is employed to decrease the overshoot and rise time during the transient response period and the fuzzy-I controller is used to get disturbance rejection and zero steady state error. Obtained results show that the proposed controller not only is robust, but also it gives excellent dynamic and steady-state characteristics compared with traditional controllers.
