Title   DSP-based AC synchronous motor controller design                   

Abstract

    As we all know, the emergence of electrical motors has brought new energy to industry civilization. Compared with traditional motors, they have the advantage of low pollution, less noise and high efficiency of energy. With more and more environmental problems these years, people tend to pay more attention to environmental protection. For achieving this goal, products such as PMSMs are highly developed, so is the control theory of these motors. This paper finishes the design of the control system of PMSMs based on this background and according to practical needs.

    Based on the tasks given by the tutor, an overall design of the system is given, and tms320f2812 is chosen as the DSP. The control panel is based on this DSP and carries on tasks such as computations or communications.

Firstly, this paper gives the introduction of the structure of PMSMs. Then, SVPWM control theory is analyzed. Hardware for a brief introduction , and then carried out mainly for software aspects of the work. The main control program and the interruption program are given in the software part and some key blocks of this area are introduced in this part.  

Key words：DSP, permanent magnet synchronous motor, vector control
