Abstract


In this paper, \For analog velocity loop defects , this improved control scheme to achieve a fully digital closed-loop speed and position control, system debugging and functional expansion were completed under this program . To ensure the performance of four synchronous motor linkage , the system uses a differential negative feedback control , and for its dynamic and static performance is analyzed theoretically . On this basis , the paper describes the functions studied backlash and friction dead zone nonlinear impact on the system , we propose a multi-motor synchronous linkage method of electrical consumer backlash and deadband compensation algorithm . In order to verify its effectiveness , this paper focuses on the bias voltage on the backlash of the simulation analysis . The results show that the system operating conditions, the value of the bias voltage can be varied to ensure the backlash corresponding results. In order to achieve high performance position tracking control , this paper analyzes the conventional PID algorithm , the introduction of an intelligent partition PID controller and carried out the actual system debugging. The results show that the system can achieve high -precision position tracking , performance has basically reached the indicator. In addition, the multi-motor synchronous linkage of fault-tolerant control provides hardware redundancy , the paper in the final for the fault-tolerant control systems for program planning and program design.
