Fuzzy Active Disturbance Rejection Electronic Governor for Marine Diesel Engine and Hardware-in-loop Simulation

摘要

Marine diesel engines operate in highly dynamic and uncertain environments, hence they require robust and accurate speed controllers that can handle the uncertainties encountered in these environments. The current speed controllers for marine diesel engines are based on PID which cannot fully handle the uncertainties encountered in such environments. Active disturbance rejection control technology can handle such uncertainties to produce a better control performance. However, active disturbance rejection controller need large numbers of parameters, some parameters of ADRC need to adjust on-line, so it is not convenient when actually operating and parameters change, thus a kind of method called fuzzy logical control is proposed. The fuzzy controller is used to modify parameters of ADRC online which improve the active disturbance rejection controller adaptive capacity. In order to verify the feasibility of the new system, marine main engine speed control Hardware-in-loop Simulation system is establish under laboratory conditions. Hardware-in-loop Simulation results show that the controller has higher accuracy and better Robustness in uncertain environments.
