Based On TMS320F2812's ISG Permanent Magnet Synchronous Motor Digital Control System Research

Permanent Magnet Synchronous Motor (PMSM) is provided with small size, good performance, simple structure, high reliability and large output torque characteristic, are widely used and valued. With the constant widening applications of PMSM, the motor control system design requirements are also increasing. At present, permanent magnet synchronous motor has been widely used in the field of automation.In the project, the electromechanical energy transformation part is the exterior-gibbose permanent magnet synchronous motor. First systematically elaborat-ed system of domestic and international car ISG development, the basic theory of permanent magnet synchronous motors and digital control system development process, the status and trends, and analysis of the structure and permanent magnet synchronous motor mathematical model, focuses on The vector control method, a comparative analysis of four different control strategies, and on vector control for a more in-depth study, and then given in the id= 0 when the motor mathematical model and its realization, then it tells the ISG control The general principles of system design. The fourth chapter in this digital control system of the core, such as current regulator, speed controller, position controller made detailed and careful analysis, and gives some mathematical model, to facilitate the performance of each loop were analyzed.Based on the above analysis and system modeling the realization of the program, developed a set of permanent magnet based on TMS320F2812 digital control system for all the experimental platform, and designed to IPM as the core power control hardware, drive system, designed based on TMS320F2812 of software system given main program and interrupt service subroutine flow chart, combined with CCS integrated development environment for the entire control system software debugging and do experiments, get the SVPWM output waveform and phase current waveform, the experiment proved The digital control system has good control performance.
