Multi-channel synchronization control based on mean of deviation coupling control

The development status of multi-channel synchronous control strategy is analyzed, and a new mean of deviation coupling control strategy based on the thought of the same given control and error compensation is presented, which can reduce complexity of the control structure with the increasing number of channels. The mathematical models of PMSM (Permanent Magnet Synchronous Motor) and load are established. The global stability and convergence of the control system have been proved according to Lyapunov stability theory. In this paper, mean of deviation coupling control strategy is applied to the synchronization control system of multi-channel, and compared with master-slave control strategy. The simulation results not only show the effectiveness of the proposed control approach, but also verify that the proposed control strategy is better than master-slave control strategy, which has better anti-interference and synchronous control performance.
