Abstract
This work presents a hardware implementation of a simple microprocessor; then uses this microprocessor to design a PI controller for PMSM (Permanent Magnet Synchronous Motor) drives. In this paper, firstly, the mathematical model of PMSM drives is illustrated. Secondly, the architecture of a simple microprocessor based on RTL (Register Transfer Level) method is proposed and the VHDL (Very high speed IC Hardware Description Language) is adopted to describe the behavior of the simple microprocessor. Thirdly, a machine code of PI controller based on the proposed simple microprocessor is designed. Finally, a co-simulation by Simulink/ModelSim is applied and verified the performance of the microprocessor-based PI controller.
