Research and Simulation on Diesel Engine Speed Control System Based on Multi-surface Sliding Mode Control

The power quality and performance of the diesel engine related to the stable operation of the ship diesel engine. In order to make the diesel engine been well emissions, economy and power performance, for control of the speed stability is very important. Because of marine diesel engine with nonlinear and time-varying, the traditional PID controller can not optimize parameters and difficult to adapt to the speed control of diesel engine under different working conditions. In this paper, the nonlinear mathematical model of diesel engine speed regulation system is established according to the experiment result. The multi-surface sliding mode controller is designed by using the theory of sliding mode variable structure control. It is simulated with MATLAB/simulink and the results show that the multi-surface sliding mode controller can well restrain system overshoot, fast track the target, with high control precision, strong robustness, etc.
