In order to quickly achieve the speed control response of permanent magnet synchronous motor(PMSM),a PMSM speed control system based on microcontroller is designed.In terms of hardware,a speed controller,photoelectric encoder,and core microprocessor are designed to collaborate.In the software section,a PMSM mathematical model is constructed to address the nonlinear and highly volatile characteristics of permanent magnet synchronous motor signals.In the constructed mathematical model,the input signal is transformed to generate a system speed measurement algorithm.Based on this,a microcontroller is used to analyze the operating status of the permanent magnet synchronous motor in different situations,achieving system speed regulation.In the simulation experiment,the designed system has a response time of only 5.8 seconds and a faster response speed.
