[Abstract]:With the development of motor technology, the demand for motor control is increasing day by day. Therefore, the research of motor control technology is of great significance. The control of three-phase AC motor system has been developed into a new subject which integrates many knowledge, including motor theory, automatic control principle, power electronics technology. Embedded system control and computer control. In AC speed regulation technology, with the need for greater speed range and faster response speed. The vector control of variable frequency speed regulation is considered to be the most promising method for its excellent performance and wide range of application. This paper introduces the PWM technology of frequency conversion speed regulation, focuses on the control technology of SPWMN SVPWM, and introduces the speed control system of asynchronous motor based on two kinds of models. Based on the dynamic mathematical model, the applicable formulas of Clark transform and Park transform are analyzed, which pave the way for the FOC vector control algorithm used in this system. The main research contents are as follows. This system adopts TMS320F28335 chip, based on its advanced floating-point operation function and high-speed operation speed, improves the speed of motor control of FOC algorithm. (2) the anti-interference optimization design is carried out according to the characteristics of anti-interference of the current general vector control circuit, and the reactor is added to the power supply of the control board, and the effect is obvious. 3 the software and hardware circuits of the whole system are designed, and some interference problems in the process of hardware debugging are described. The feasibility of the system is proved by the experimental results.
