Speed Control of Electric Vehicle Considering Topographic Data

The Electric Vehicle is a new age technology which reduces pollution and use of fossil fuel. With increasing awareness about climate change, the focus is increasing on Electric Vehicle in India. In this paper different forces acting on the Electric Vehicle are studied and an appropriate model is developed. A Proportional Integral Derivative (PID) controller whose gains are tuned by an optimisation technique namely Cuckoo Search is implemented to control the speed of the Electric Vehicle. For the practical analysis of road and vehicle, the slope information is obtained. Also a Pulse Width Modulation (PWM) inverter is designed to supply voltage to the three phase induction motor in the closed loop system. The model is validated on different speed profile trajectories and by varying friction coefficient of the road. The simulation results establish that the proposed controller is robust with enhanced performance because of using the actual slope conditions of the road and can be implemented effectively in the Electric Vehicles
