Permanent magnet synchronous motor (PMSM) vector control systems are widely used in servo applications due to their ability to achieve high precision, high dynamic performance, and wide-range speed or positioning control. This paper introduces the mathematical model of the PMSM, various current control strategies, and presents a general design scheme for a digital PMSM servo system, along with its simulation and experimental waveforms. Sensorless permanent magnet synchronous motor control systems are currently a research hotspot.
With the development of new materials, mechatronics, power electronics, computers, control theory, and other related new technologies, AC servo systems for permanent magnet synchronous motors have expanded into a wide range of applications, achieving high-speed, high-precision, high-stability, fast-response, and energy-efficient motion control.
In hybrid power systems, the motor is the hub of the entire system, and its performance directly affects the final performance of the entire system and pollutant emissions. Taking the AC permanent magnet synchronous motor as the research object, the hardware and software design of the drive system in its controller is carried out. Simulation of the control system is performed using simulation software to verify the correctness and feasibility of this drive system design.
With the rapid development of the hydrogen fuel cell vehicle industry, the market prospects for high-speed air compressors are increasingly promising, and their drive motors mostly adopt permanent magnet synchronous motors. As the drive control system of air compressors, the performance of high-speed permanent magnet synchronous motor drivers is crucial. Currently, the future development trend for high-speed motor drivers is towards higher power and higher speed, with commercial vehicles and large trucks being their main application scenarios. The development of high-power high-speed motor drivers is imperative. This paper focuses on the design of the hardware system of a high-speed permanent magnet synchronous motor driver, providing a practical verification platform for its software algorithm. 1.
