Description of the research topic:
Nowadays switched reluctance motor (SRM) drives have been widely used in the field of controlled electric motor drives. Switched reluctance motors are double-salient, single excited motors. Due to high starting torque and good efficiency SRM drives are suitable to be applied in electric vehicles and cars.
Main blocking factor of wider application of SRM drives is the significant torque and current ripple appearing at the commonly used simple control methods. This makes difficult not only the realization of high performance (fast and overshootless) speed control but causes strong noise as well. All these problems can only be solved by using control depending on the drive state such as motor speed and torque.
Purpose of this research work is simulation investigation of a switched reluctance drive and determination of the optimal control such as optimal switch on and off angle and current reference signal in the function of motor speed and load. Cost function can be determined by using efficiency and harmonic content of torque at optimal state searching. Investigation of the drive speed control can be executed after this.
The up-to-date control theory and the computer hardwares make the application of adaptive control possible, taking the actual parameters of control circuit changing during the operation into account. For controlling electric drives, algorithms ensuring fast adaptation and having simultaneously a fairly few calculation requirement can be applied effectively.
