The study aims to reduce the production cost and improve the electromechanical management level of enterprises.A switching type reluctance drive system based on Advanced Virtual RISC (Reduced Instruction Set Computer) (AVR) is designed.In addition, the control circuit of the switched reluctance drive (SRD) system needs to be designed.Control circuit design includes the minimum system of the Single Chip Microcomputer (SCM), position sensor circuit, position signal channel, current detection circuit, and current simulation control circuit.Among them, the current simulation control circuit is the most critical hardware.The performance of the designed SRD system is tested through simulation experiments.The results show that when the rated speed is lower than 750 rpm, the rotation multiple is between 1.5 and 2. And when the speed is slow, the matrix output ability will be better.When the speed ratio is 20% more than the rated value, the matrix output ability has 1.32 times the ability of the torque.It can be concluded that the torque output trend and matrix output value conform to the requirements of matrix performance.Combined with the test results of the current waveform, the SRD system based on the AVR microcontroller has excellent control and detection ability.The study provides a technical reference for the design of electromechanical control system and plays an important role in developing the electromechanical measurement and control system.
