基于MC56F8346控制器的塞拉门控器研究

摘要

The design of a sliding plug door control unit for high speed train based on MC56F8346 controller is introduced. Brushless DC motor is controlled by using speed and current double closed loop mode in the controller, and the speed regulator and current regulator are controlled by PI controller. The safety relay and state machine are adopted separately in design to increase safety and reliability of sliding plug door moving. The hardware block diagram and software control algorithm are given. The test results indicate that the design of the plug door controller for high speed train can meet the system requirements.%介绍了一种基于MC56F8346控制器的高速列车塞拉门控器的设计。其控制器采用速度、电流双闭环方式实现对无刷直流电机的控制，速度调节器和电流调节器均采用PI控制器控制，设计中分别运用了安全继电器及状态机来增加塞拉门运行的安全性和可靠性。给出了硬件框图以及软件控制算法。试验结果表明，所设计的高速列车塞拉门控制器能满足系统要求。
