Abstract:

According to the salivation unit's multi-motor synchronous control system of nonlinear, time varying, load disturbance and other vulnerable features, neural network PID controllers were designed and a strategy of realtive coupling control for multi-motor synchronization based on neural network PID contorl was proposed;Simulation results show that: the control algorithm has a good stability behavior and robust performance ,a quick convergence rate and can achieve the multi-motor synchronous control of salivation unit effectively compared with the traditional control strategy.
