Design of the AC Motor Speed Regulator Controlled by ARM

The paper proposes an AC motor speed regulate system based on ARM. The system's hardware core is the LPC2131, in which processor successfully transplanted the mu C/OS-II real-time operating system. In the form of task, each functional module of the system can be achieved on the processor LPC2131. The system is simple hardware circuit, software module to realize the complex control algorithms. Experiments show that the multi-task classify program is feasible on the embedded real-time operating system based on LPC2131 and mu C / OS-II, it ensures the system's real-time, has good multi-task operating and transferring characteristics and improves the system stability and reliability.
