With emphasis on a cleaner environment and efficient operation, vehicles today rely more and more heavily on electrical power generation for success. In this paper, to improve the speed performance of the drive against uncertainties caused by load disturbances, an integral switching surface couple mode speed controller was proposed. As such, mathematical modeling of the HEV components as the three phase induction motor coupled to the DC motor in hybrid electric vehicle was introduced. The controller of the ‘induction motor’ (IM) was designed based on input-output feedback linearization technique. It allowed greater electrical generation capacity and the fuel economy and emissions benefits of hybrid electric automotive propulsion. Hybrids transient torque allows the use of start/stop operation as well as brake energy regeneration. Thus, the results of Matlab-Simulink simulations and a comparison between the control schemes are presented.
