Título del libro: International Power Electronics Congress - Ciep Título del capítulo: Test Bench to emulate an electric vehicle through equivalent inertia and machine dc
In this article is proposed an approach to study electric vehicles based
on an experimental platform that adequately reproduces the behavior of
electric vehicles by obtaining the correct equivalences between a
vehicle and a test bench. In the first part the general dynamic equation
of movement of a vehicle is stated, then how to obtain an equivalent
dynamic equation for test bench that represents every one of the
variables of the dynamic equation of movements for a vehicle by using a
test bench is proposed. The system is constituted by an induction motor
(tested motor), associated to the mechanical part through a transmission
(bands), inertia (two wheels of automobile, pulleys and arrows) and a CD
motor-coupled to the induction motor. Finally the simulation results for
the models of the proposed system, as well as experimental results that
show the possibilities of variation of the test bench under some
conditions of operation are presented. These simulations were made in
Matlab/Simulink and the tests were made using the TXS320F2812 DSP.
