Mid-range Deviation Coupling Control for Multi-motor Speed Synchronization System
The synchronization accuracy of a multi-motor speed synchronization system is influenced by the motor control algorithm and synchronization control strategy.In response to the shortcomings of existing control strategies,a mid-range deviation coupling control strategy for multi-motor speed synchronization systems was proposed.Firstly,a mathematical model of multi permanent magnet synchronous motor was established.On the basis of the deviation coupling control strategy,the motor speed deviation was calculated using mid-range speed,and the structure of the deviation coupling control was optimized.The controller was designed using a nonsingular Terminal sliding mode control algorithm.Then,the Lyapunov stability theory was used to analyze the stability of the designed controller.Finally,a multi-motor synchronous control test platform was established for test verification,and the test data was analyzed.The results show that the proposed control strategy is effective and can improve the synchronization performance of the system.
