Drive Control of a Class of Scan Systems

In order to meet the requirements of the degree of speed stability for scanning motion, a three-phase AC permanent magnet synchronous motor (PMSM) driven by sinusoidal wave was utilized as the actuator to design a drive control system for a class of scan systems. The main performance index，the degree of speed stability was introduced in brief. With the method of parameter matching, the design of rotating speed and torque, the system was realized. The structure and system components were designed. The simulation results show that the designed control system can achieve desired degree of stability and satisfy the performance specifications effectively and rapidly.
