碩士 === 國立成功大學 === 工程科學系碩博士班 === 90 === This thesis presents the analysis and implementation of a DSP-Based speed and position control system for permanent-magnet synchronous motors. It first converts the componenet of stationary frame to the synchronously frame. This conversion simplifies the dynamic model of the permanent-magnet synchronous motor for carrying out analysis, simulation, and control system implementation. The control accuracy of the conventional analog control systems is poor and maintainess is not easy. Thus, in this thesis, implementation of the control system is based on a digital signal processor. A digital control system for a 200W AC permanent-magnet synchronous motor is realized through fixed-point digital signal processor (DSP TMS320F240), and based on the programming skill, the floating-point operation can be implemented easily. Its internal functions are adaptive to the motor control. In addition to those advantages, it can also simplify control circuits, lower the cost, and increase reliability of the systems. The hardware implementation of this control system only includes power supply, driver and current feedback circuit. The rest of parts are realized by the software.
