ABSTRACT

The ship main engine speed control system is a typical nonlinear system and it is uncertain characteristics, It is influenced by the wind, wave, flow etc. So it is difficulted to designed the diesel engine mathematical model. This paper presents a nonlinear mathematical model of ship main engine. Because the active disturbance rejection controller does not depend on the mathematical model of the system, this paper attempts to use the ADRC control technology to marine main engine speed controller. And fuzzy controller is used to modiffy the ADRC parameters to improve the adaptive ability of active disturbance rejection controller; So it is designed the fuzzy ADRC controller of ship main engine adaptive. The simulation results show that the ship main engine speed fuzzy ADRC controller has strong robustness, and speed switching is fast and smooth, so it can achieve high precision speed control.
