Abstract: To solve the instable and backward control of ceramic shuttle kiln, a hybrid intelligent control method for ceramic shuttle kiln is proposed. A hybrid intelligent model for the sintering process of ceramic shuttle kiln is also established. Sintering temperature curve of a kind of ceramic products is obtained from the knowledge base of expert control system. In the meantime, Kalman filtering algorithm is given. Kalman filter-based PID hybrid intelligent controller is designed by combining traditional PID control method with Kalman filtering method, so as to realize the intelligent temperature control for the sintering zone of ceramic shuttle kiln. MATLAB-based simulation results demonstrate the effectiveness and feasibility of the controller designed.
