Abstract
A control method based on fuzzy active disturbance rejection controller is proposed and applied to the three-motor synchronous control system, which can adjust the parameters automatically by using the inferential capability of fuzzy control. Double channels compensation of extended state observer is used to estimate and compensate the total disturbance of the system and the coupling between speed and tensions, thus an approximate linear and determinable system is obtained. Experiments about decoupling property, tracking performance and anti-disturbance performance are conducted on the platform constructed by combining with SIMATIC S7-300 PLC. The results prove that the control system has better performances in dynamic and static character, stronger anti-interference ability and better robustness than traditional PID control system.
