Abstract

With the development of science and technology, people have higher and higher requirements for the stability of high-precision servo systems. In this paper, the principle of dual-motor anti-backlash is studied. By modeling the mathematical characteristics of the whole servo system, the drive control block diagram of the dual-motor is designed. Finally, the servo system model of the dual-motor anti-backlash transmission is established by MATLAB. Based on the servo system model, the control algorithm of the system is designed, and the fuzzy-PID control algorithm is designed in the position loop. According to the threshold of the system, a more suitable control algorithm is selected to improve the stability and robustness of the system. A new anti-backlash method for improving the constant bias torque is designed, and the model of the anti-backlash module is designed. Finally, through simulation verification, it is concluded that the fuzzy-PID control strategy can effectively reduce the overshoot of the system, and the added anti-backlash module significantly improves the stability of the system.
