二阶自抗扰控制器在三电机同步系统中的应用
Second-Order Active Disturbance Rejection Controller Applied in Three-Motor Synchronous System
摘要
Abstract
On the basis of mathematical model analysis of the three-motor synchronous control system,combined with characteristics of active disturbance rejection control theory,a new control method based on second-order active disturbance rejection controller(ADRC) is designed and applied into the synchronous control of three-motor variable frequency speed-regulating system.Three second-order ADRCs are designed for speed control loop and two tension control loops to achieve system dynamic decoupling between speed and tension.In the second-order ADRC,the internal interference in system model,the external disturbance and the coupling effects between speed and tension are made as a total system disturbance by extended state observer,and the extended state observer is used to estimate and compensate the total disturbance of the system.Three experiments of decoupling property,tracking performance and anti-disturbance performance are completed on the platform based on SIMATICS 7?300 power PLC.The results show that second-order ADRC can realize the decoupling control of speed and tension in three-motor synchronous system,improve the anti-interference ability,and make the system has stronger robustness.关键词
