INTRODCTION
Under the pressure of environmental protection and
petroleum resource exhaustion, the development of electric
vehicles are becoming more and more necessary all over the
world. Evs are playing an important role in solving those
problems, which are caused by internal combustion engine
vehicles (ICVs). From the viewpoint of electric and control
engineering, EV has some advantages over ICV. For example,
its torque generation is very quick and accurate, and its output
torque is easily comprehensible, and its motor can be
distributed for several wheels [1][2].
MATHEMATIC MODEL
The electric vehicle’s regenerative braking control system
in this paper is composed of (i) energy source, (ii) DC-DC
power converter using IGBT to control the power into and out
of the battery bank, (iii) permanent magnet DC motor, and (iv)
DSP controller. Figure 1 shows the instantaneous power
structure topology of regenerative braking of DC motor.
CONCLUSION
In this paper, we have presented a H• robust controller for
electric vehicle actuated by permanent magnet DC motor.
Experimental results have confirmed that the performance of
the proposed controller is quite robust and insensitive to
system parameters and load changes. H• control algorithm is
employed to efficiently attenuate the effects on the tracking
error due to external disturbance. Moreover, the proposed
controller is employed to improve the drive range of electric
vehicle.
