Multi-motor Synchronous Control Based on Fuzzy Adaptive Backstepping Algorithm
In multi-motor system,parameter perturbation and load torque variation will affect the tracking accuracy and speed synchronization of the whole system,so a fuzzy adaptive backstepping control method is designed.The three motors adopt the structure of average deviation coupling.The average value of the speed is processed and then the synchronization effect of the system speed is further enhanced through the speed error compensator.The fuzzy adaptive backstepping algorithm is applied to the control structure to adjust the speed error caused by the disturbance accurately.Compared with the traditional sliding mode algorithm and the traditional backstepping algorithm in the simulation experiment,the results show that the fuzzy adaptive backstepping control strategy has the characteristics of high precision,low synchronization error and good anti-interference performance.
