A simulation study of switched reluctance motor driven by a PID controller

Although, the switched -reluctance motor (SRM) drives are still at development stage, their applications are projected to grow very fast. The switched- reluctance (SR) motors excels at very low end of the speed being able to provide high torques with excellent dynamic capability, and at very high speeds due to its robust rotor. Acoustic noise is an area where SR technology has made the greatest advances in recent years due to a combination of electromagnetic design elements, electronic techniques and attention to mechanical design. SR systems are used in clothes washers, food processors, vacuums, power tools and other high performance applications. The SR motor is a variable speed machine. Its torque and speed may be controlled by controlling the excitation time or modulating the excitation with suitable feedback signals. In industrial automation fields, conventional PID control is acting a very important role, but its robustness is very weak. In this paper, the basis of PID controller technique is introduced. A PID controller is a feedback controller where the output of the controller is based on the summation of the proportional gain KP multiplied by the error, the integral gain KI multiplied by the integral of the error, and the derivative gain multiplied by the rate of change of the error. The objective of this project is access the applications PID controller in SR motor control using simulink.
