Application of Fuzzy Adaptive PID Control System in Hopper Dredger Active Head

In order to reduce the operator＇s work intensity and improve the initiative trailing suction hopper dredger rake head automatic control response speed, accuracy and stability, through the analysis of the structure and working principle of the active rake head, the kinematics model of active rake head is established, a fuzzy adaptive PID controller based on active rake head features is designed according to the features of active head, the application of the PLC to achieve the controller is researched. Using MATLAB to make a simulation for controller, which results show that the controller has good speed, robustness and stability.
