In this thesis, the development and control for switched-reluctance motor (SRM) drive powered by a three-phase single-switch switch-mode rectifier (SMR) are studied. All the controls of these two power stages are realized fully digitally using digital signal processor (DSP). First, in the design and implementation of SMR, the power circuit components and switching scheme are properly designed to let it be operated under discontinuous current mode (DCM) at any case. The satisfactory line drawn power quality can be obtained, and it can provide well-regulated and boostable DC-link voltage for the followed SRM drive. Second, in the developed SRM drive, the hysteresis current-controlled pulse width modulated (CCPWM) scheme is designed to obtain robust winding current tracking control. And the randomly varying hysteresis band is applied to reduce the SRM stator vibration and acoustic noise. In speed control, the SRM drive dynamic model at a chosen nominal case is estimated. And a two-degrees-of-freedom control scheme is designed to let the motor drive possess the defined reference tracking speed responses. As the operating conditions are changed, a variable-structure system (VSS) tracking error regulator is developed to reduce the model tracking error. Moreover, the speed deviation due to load torque change can also be significantly reduced. Finally, the performance evaluation for the whole SMR-fed SRM drive system performance is evaluated experimentally.
