摘　　要：针对电涡流测功机的扭矩加载实验问题,开发了一种基于ARM的嵌入式控制器。选取TM4C微控制器为CPU,以功率MOSFET为功率驱动器件,利用PI算法,采用RTX实时操作系统实现了对电涡流测功机扭矩加载的闭环控制,并结合电涡流测功机进行了扭矩加载实验。实验结果表明:该控制器具有加载性能好、结构简单及可靠性高等优点,具有较高的工程应用价值。Aiming at the torque-loading problem of the reddy current dynamometer, a new embedded controller based on ARM is devel oped, which takes TM4C as the CPU and power MOSFET as power driver. The design achieves closed-loop control of torque-loading controller for reddy current dynamometer using the PI control algorithm and RTX real-time operating system. The experiment results show that the controller has the advantages of high loading performance, simple structure, high reliability and so on, and it has great value in engineering application.
