Single-phase induction motors are simple in construction, cheap in cost, reliable and easy to repair andmaintain. Many controllers were designed to control the speed of a single-phase induction motor, but they aresensitive to plant parameter variations and disturbances. Speed control with very less transient responserequires non-linear and robust control methods. Sliding mode control is one of the robust control techniqueswhich is insensitive to disturbances. Here we propose a higher order sliding mode (SM) observer-basedcontroller for a single-phase induction motor. The applied control depends on the dynamic model of theinduction motor. The controller is structured by applying a blend of input linearization strategy and higherorder sliding mode calculation with consistent estimation of rotor speed and stator currents, which limits thevulnerabilities continuously and lessen the chattering phenomenon in the control effort exertion utilizing asuper twisting algorithm.
