A novel method for the control of multi-motor system based on embedded terminal
In order to synchronize the multi-motor system, a novel method for this system based on CAN bus and embedded control terminal is presented in this paper.A controller of the electric vehicle with multi-brushless-DC-motor system is designed, and 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, master controller and sub-controllers, on this platform every in-wheel motor could be driven independently via the CAN bus.The control terminal is used to control the moving status of the EV.The control terminal chooses open-coded, occupies the hard real-time inner-core μC/OS-Ⅱ, transplants open-coded graph bank μC/GUI and uses touch panel as the input device.At the end of this paper, the experiment results verified that the multi-motor system is reliable, the control strategy is rational, and the electric vehicle applied this multi-motor system has better dynamic response and higher reliability.
