Abstract: The transmission characteristics of medium and small logistics machinery in the working process can effectively feedback the working conditions of the machinery, the optimization design of transmission control can improve the overall stability of medium and small logistics machinery. A new control method of medium and small logistics machinery based on variable structure fuzzy PID and steady state regulation is proposed. The controlled object model and control constraint parameter model of medium and small logistics machinery control are constructed. The fuzzy PID variable structure control method is used to optimize the control algorithm of mechanical transmission. Combined with steady error tracking and inertial fusion of transmission system, Kalman filtering is carried out to reduce the output steady state error of logistics machinery and realize the optimal design of control rules. The hardware of the control system is designed under the embedded ARM environment. The main control circuit module, the embedded control module and the integrated information processing module are designed optimally. The test results show that the control system can effectively realize the control of medium and small logistics machinery, and the quality of the control is good.
