Özet:

This paper presents the development of a mathematical model of a small electric vehicle which is propelled by permanent magnet direct current (PMDC) motor. The tractive force required to drive the vehicle is obtained from (PMDC) motor. The torque-speed characteristics of the motor are used to obtain tractive force at given vehicle load and floor conditions.  The simulation model of the vehicle for acceleration is developed, considering various forces that are acting in favour and opposite to the vehicle acceleration and also floors having different slopes. The vehicle parameters used in the simulation are determined beforehand. The vehicle acceleration model is simulated in MATLAB for various floor slopes and simulation performance results are presented for the vehicle that is moving on floors like flat, upslope, downslope, and more.
