Abstract
Aiming at the speed and tension being difficult to decouple for the three-motor synchronous control system, a mathematical model of three-motor synchronous control system is analyzed, and a control strategy on the basis of active disturbance rejection control(ADRC) technology is proposed. According to the characteristics of three-motor synchronous coordination, it designed a fuzzy one-order ADRC speed controller and a second-order ADRC tension controller. By designing the S7-300 three-motor coordinated control system experimental platform, the speed control performance and the decoupling performance were tested. The results show that three-motor synchronous control system controlled by the fuzzy ADRC improves the dynamic performance and steady-state accuracy by comparison to the traditional PID control system. It makes the speed and tension decoupled, and tension and tension decoupled. Its control performance is high and stable.
