CMAC-PID integrated controller used in marine propulsion plant

Abstract

By using the quasi steady state and mixed modeling methods, the nonlinear mathematical model of the ship main propulsion system is established. An improved integrated control algorithm based on CMAC and PID is presented in the ship propulsion system. Simulation computing is completed to investigate the dynamic characteristics of the ship propulsion system on rough sea conditions. The results show that the combined control algorithm possesses a high tracking and anti-disturbance capacity and it brings better control effects than traditional PID controllers. Therefore, it can effectively improve the turbocharger surge caused by the oversized rotation speed oscillations in ship propulsion system.
