This dissertation investigates the performance improving methods and the pratical applications of micro permanent magnet synchronous motors. In this dissertation, first, a novel state estimator is proposed to obtain the estimated rotor position or rotor speed of the micro motor. By using this proposed state estimator, a wider range of adjustable speed control system and a more precise position control system can be achieved when compared with using the micro encoder, which is attached to the micro motor.
In addition, an adaptive inverse control and an optimal control are designed and implemented for the micro permanent magnet synchronous motor. The proposed control methods can improve the transient reponse, load disturbance capability, and tracking ability of the closed-loop micro permanent magnet synchronous motor systems.
A digital signal processor, TMS320F28335, which is made by Texas Instrument Company, is used as the control center to excute the state estimator, control algorithoms, and coordinate transformation. As a result, the hardware is simple. Experimental results show that the proposed methods can effectively improve the performance of the micro permanent magnet synchronous motor drive systems. Finally, a multi-dimentional position table is controlled by using the implemented system. The experimental results show the feasibility of using the proposed micro permanent magnet synchronous motor drive system in a practical application.
