Abstract

A novel flux-linkage controller using sliding mode technique with integral compensation (SM-I) is proposed for torque ripple minimization of a switched reluctance motor (SRM). The proposed SM-I controller inherits the advantages of proportion-integration (PI) and conventional SM controller. These make it feasible for the flux-linkage controller to reduce torque ripple by correctly selecting the flux ramps in the limit of available dc-link voltage. Moreover, since the controller is not model-based, it avoids the complexity of mathematical modeling and is easily implemented. Experimental results demonstrate that the proposed controller performs better and can be used as an alternative for nonlinear SRM drive systems.
