Abstract
With the development of material technology , power electronics technology, control theory, computer technology, micro-electronics technology and the improvement of motor manufacture level, permanent magnet synchronous motor (PMSM)alternating current (AC)servo systems are widely used in all kinds of industry areas.
In this paper , based on a digital signal processor TMS320F2812, a controller for PMSM is researched and designed. And based on the analysis of the structure and vector control model of PMSM，establish a vector control system of PMSM. The whole hardware structure of PMSM AC servo system and the lately TMS320F2812 DSP made by Texas Instruments Incorporated are analyzed. Design the main circuit of system, including three-phase rectifier circuit, filters, brake circuit and power inverter. Focus on making a description of the circuit design and realization of the control panel,and design the TMS320F2812’s schematic and PCB board based on the protel software. design the system’s control software, And give the main flow chart. C language and assembly language are be used to mixed Programming. Achieve the communications between the DSP and the touchscreen.
Keywords：PMSM the vector control DSP touchscreen
