Speed Control of Switched Relectance Motor with DSP controller

Speed Control of Switched Relectance Motor with DSP controller
In construction, the switched reluctance motor (SRM) is the simplest of all electrical machines and most rugged one. The highly non linear relationship of the SRM are due to its single excited (exciting the stator only) double- salient and highly nonlinear machine characteristics. SRM drives can be controlled only by synchronising the energisation of the motor phases with the rotor position. Hence, the control of SRM is a tough one to deal with.

The increase in need for variable speed drives in industry and consumer application has seen renewed interest in the SRM. SRM is widely used in high performance servo applications such as aerospace, industrial and robotics.

SRM cannot be run directly from the supply. It can be run only when the motor is integrated with power converter, controller and rotor position sensor. So its essential to design high performance digital controller for SRM to get the optimum performance in the presence of the parameters variations and load disturbances.

The best solutions to control a switched reluctance motor is the usage of TMS320C24x. This new DSP family enables cost-effective design of intelligent controllers for switched reluctance motors. A novel speed control
algorithm is used to allow the Switched Reluctance motor drive to reach high efficiency, smooth operation, very good dynamic behavior, very high speed and low accoustical noise. All these solutions use only TMS320C24x resources, thus providing a single chip cost efficient control structure.
