| Summary: | 碩士 === 國防大學中正理工學院 === 電子工程研究所 === 94 === The thesis primarily investigates the sensorless DVD spindle motor control based on vector-control theory and the extended Kalman filter. Firstly, the mathematical model derivation and the vector control design of the DVD spindle motor are introduced. Then, the estimation theory of the extended Kalman filter and the estimation speed of the spindle motor are introduced. Finally, the analysis of the simulation results obtained with and without load under different speeds by using MATLAB/SIMULINK programming is referred to hardware implementation.
The experiment is based on the DS1104 development system produced by dSPACE company, cooperated with driver and current-feedback circuit, using the estimation speed obtained through the extended Kalman filter as the feedback speed, then associated with other software and hardware to perform the sensorless DVD spindle motor control.
