First, a rotor position estimating technique is presented. By measuring voltages and currents of the motor, and then compute the extended flux linkage, the rotor position and speed of the motor can be estimated accurately. The position estimation is simple and is obtained by only calculating the extended flux linkage. The estimating technique is not strongly related to the parameters of the motor. In this dissertation, the estimating technique is used to both the constant torque region and the field weakening region. Next, two nonlinear control schemes including input-output feedback linearization controller and adaptive backstepping controller, are proposed for the IPMSM drive system. The IPMSM drive system can be improved by using the two control schemes. In addition, a fast transient response, good load disturbance rejection capability, and satisfactory tracking ability can be achieved. Both the nonlinear control schemes can be applied to the speed control system of the IPMSM drive system based on the proposed sensorless method. Finally, a Texas Instruments digital signal processor, TMS320LF2407, is used to execute the rotor position/velocity estimation, space vector pulse width modulation, and speed control. As a result, the hardware is very simple. Several experimental results and simulations show the correctness and feasibility of the proposed drive system. none 劉添華 2009 學位論文 ; thesis 189 zh-TW |
