Abstract
Motors have a wide range of applications in various aspects such as automotive, medical, industrial production, etc. Commonly used motors can generally be divided into DC motors and AC motors.Permanent Magnet Synchronous Motor (PMSM) is a type of AC motors with strong starting ability, high peak efficiency and high reliability, and with greater application value. This paper mainly studies the control technology of PMSM, and designs a set of motor controller and its protection system based on FPGA. First, based on the development and simulation platform of FPGA, the important algorithms of the motor controller and protection system are simulated and analysed. Then the system is built in the actual environment. Through actual testing, the speed control of the motor can be accurately achieved and various fault protection and instructions of the motor controller can be realized. The system is based on the development platform of FPGA, which with fast running speed, high flexibility, short development cycle, high resource utilization rate, and strong portability.
