Description: As traditional control schemes, open-loop Hysteresis and closed-loop pulse-width-
modulation (PWM) have been used for the switched reluctance motor (SRM) current controller. The Hysteresis controller induces large unpleasant audible noises because it needs to vary the switching frequency to maintain constant Hysteresis current band. In contract, the PWM controller is very quiet but difficult to design proper gains and control bandwidth due to the nonlinear nature of the SRM. In this thesis, the ac small signal modeling technique is proposed for linearization of the SRM model such that a
conventional PI controller can be designed accordingly for the PWM current controller.

Description: This program has been written using Matlab/Simulink software. It can be used to find out the behavior of the induction motor behaviore when fed from a PWM inverter. The program is written so that the user can simulate any induction motor he wants by just loading the electrical and the machanical parameters in the workspace. The induction motor is modelled by the 7th order dq model which takes the iron loss component into account. The motor works in open loop but the closed loop can be easly performed by just adding the vector controller or any other controller and a PI speed controller.-This program has been written using Matlab/Simulink software.

Description: The induction motor is fed by a current-controlled PWM inverter which is built using a Universal Bridge block. The motor drives a mechanical load characterized by inertia J, friction coeficient B, and load torque TL . The speed control loop uses a proportional-integral controller to produce the quadrature-axis current reference iq* which controls the motor torque. The motor flux is controlled by the direct-axis current reference id*. Block DQ-ABC is used to convert id* and iq* into current references ia*, ib*, and ic* for the current regulator. Current and Voltage Measurement blocks provide signals for visualization purpose. Motor current, speed, and torque signals are available at the output of the Asynchronous Machine block.-The induction motor is fed by a current-controlled PWM inverter which is built using a Universal Bridge block.
