Abstract :
We present a fuzzy logic-based precompensation method for PI controller to improve the temperature control performance for a variable capacity heat pump. The presented control scheme is composed of a fuzzy logic based compensator and a conventional PI controller, which are serially connected. The fuzzy precompensator is designed to improve the control performance by considering the nonlinear and asymmetric characteristics of the system. The experimental results show the effectiveness of the presented control scheme
