Multi-Motor Control

In order to synchronize the multi-motor system, a novel method for this system based on embedded control terminal. A controller of the strategy with the function of synchronous control is also completed. According to the requirements of this system, a distributed control structure which based on Hierarchical Approach is chosen. The hardware platform of this structure is composed of embedded control terminal motor could be driven independently. The experiment results verified that the multi-motor system is reliable, the control strategy is rational applied this multi-motor system has better dynamic response and higher reliability.
