In recent past years, growing carbon emission caused by vehicle and scarcity of oil resources gives attention of all researchers to investigate low pollution, improved fuel economy type vehicle such as Hybrid Electric Vehicle (HEV). In this paper nonlinear hybrid electric vehicle speed control using different control techniques has been employed to improve the efficiency of vehicle by throttle position control. The controller like Proportional-Integral-Derivative (PID), Artificial intelligence based fuzzy controller, robust controller (H∞) and their comparative performance analysis has been done on the basis of rise time, settling time, and zero steady error in MATLAB-Simulink.
