[Abstract]:Aiming at the demand of low voltage and high speed motor drive system in the field of vehicle driving, the paper designs and implements the TMS320F28XX based on TI and the CPLD of ALTERA as the main control unit. The 16 bit high precision photoelectric encoder is used as the main control unit. Hall sensor combined with A / D conversion chip AD7606 as speed and current acquisition unit and Mitsubishi intelligent power module as power drive unit a low-voltage high-speed permanent magnet synchronous motor drive system. The hardware design scheme of the system is introduced in detail, including the main control circuit of DSP and CPLD, the signal detection circuit, the power drive circuit and the related hardware protection circuit. By using a method of speed piecewise searching table, the smooth speed regulation of the system from low speed to high speed is effectively solved, and the protection scheme combining hardware and software is designed by using vector control algorithm and SVPWM technology. The high performance speed modulation of the permanent magnet synchronous motor drive system is realized. The test results show that the system has the advantages of rapid response, high steady-state precision and strong anti-jamming ability.
