Abstract
Aiming at the problem that the synchronous control performance of multiple motors in a complex industrial production process control system is easily affected by motor parameters and load disturbances. The traditional speed compensator in the adjacent cross-coupling structure of multiple motors is reasonably improved. In view of the effect of motor parameters on synchronization performance, by adding a synchronization coefficient related to rotational inertia to the speed compensator. The integrity of the system is increased, and the effect of different motor parameters on the system synchronization performance is suppressed. Aiming at the influence of internal and external disturbance factors on the synchronization performance, a method of replacing the fixed compensation gain in the speed compensator with a fuzzy PID controller is proposed and designed. The anti-interference of the system is improved, and the influence of internal and external interference on the synchronization performance is suppressed. According to the simulation results, the difference from the traditional synchronization error speed compensator is that the improved synchronization error speed compensator effectively reduces the influence of motor parameters and interference on the system synchronization performance. The synchronization error among motors of the system is decreased, and synchronization performance of the system is improved.
