Multiple motors synchronization based on active disturbance rejection control with improved adjacent coupling

In this paper, an improved adjacent coupling control scheme combined with integral sliding mode control (ISMC) and active disturbance rejection control (ADRC) techniques is proposed for multiple motors synchronization. The whole synchronous system is divided into two parts. For the first part, a speed synchronization controller is designed based on an integral sliding mode control (ISMC), and an improved adjacent coupling scheme is developed by introducing coupling cofficients, which can enhance the synchronous performance of multiple motors. For the second part, an active disturbance rejection control (ADRC) technique is employed for the design of the speed tracking controller to guarantee the strong robustness and high precision. Simulation results show the effectiveness of the proposed control method.
