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