Adaptive Integral Sliding-mode Control for Multi-Motor Speed Synchronization

The work aims to solve the inherently slow convergence speed and shaking matrix of traditional exponential reaching law method, thus improving the control accuracy of multi-motor synchronous control system. Based on the structure of adjacent cross coupling control system, the adaptive integral sliding-mode control algorithm was adopted and a strategy for synchronous control over multiple speeds of synchronous motors was proposed. The simulation results showed that, the actual speed of motor could rapidly track reference speed and the synchronization error was 0. Such strategy can improve the synchronous tracking performance and anti-disturbance performance of multi-motor synchronous control system, and enhance the synchronous coordination control ability of the system.
