Magnetic Field Oriented Control System of AC Asynchronous Motor Based on DSP

摘要

This paper presents a vector control method of AC asynchronous electric motor based on the Digital Signal Processor(DSP) and establishes a mathematical model using double closed-loop decoupled vector control system analysis. The hardware structure, control algorithm and software design flow of the system are described. The key circuit, control circuit and assistant circuit are designed to implement the function of the system. Simulation and experiments show that this system is of high control precision and good dynamic performance.
