Abstract:
In view of the complex working environment of the air-suction potato planter, the conventional PID controller is difficult to achieve stable seed supply for potatoes due to its slow response, weak anti-interference, and large overshoot. Combining the advantages of repetitive control compensation and CMAC, this paper designs a PID control strategy for stable potato seed supply based on repetitive control compensation and CMAC, which is used to realize the stable seed supply of potato. The simulation results show that the composite PID control method improves the response speed of the system, improves the tracking accuracy of the system, and enhances the anti-interference ability of the system compared with the CMAC and the conventional PID parallel control method.
