Research About Servo System With Three-phase Permanent Magnet Synchronous Machine Based On DSP

For along time, because of the non-linearity, time-variety and heavy-coupling of the variable, it is difficult to control and change the rotate speed of the Alternating Current(AC) motor with variety of the frequency, Direct Current motor was used as the most important drive equipment in the much electric drive domain. The problem of the AC motor was solved with the appearance of the vector control theory in Germany in1970s. By the advancement of the technology in motor making, electric power and electron, microprocessor, especially lots of the new high-power electron elements, all of which become the physical foundation of the AC timing control system. Based on the itself characteristic, the Permanent Magnet Synchronous Machine(PMSM) will be the first drive equipment to orientate exactly and drive low-power machine.The mainly contents of this dissertation include the vector control theory, hardware and software of a PMSM AC control system and the emulating with the Matlab/Simulink. In this dissertation, we design the hardware system of the AC control system with the control chip:TMS320F2812 of the TI company and educe the circuit diagram of the control system; design the software system of the AC control system with the CCS2000 of the TI company and educe the soft flow charts and the key programme. Emulate the AC control system with the Matlab/Simulink in order to validate the correctness and feasibility of the control arithmetic and system's configuration.
