Abstract:
The imperative drive for evolution within the electric vehicle (EV) sector, aimed at pro moting clean energy generation, has yielded remarkable advancements in recent times.
Among these advancements, plug-in hybrid electric vehicles (PHEVs) have emerged as
a notably favorable option. The subsystems of PHEVs comprise of Integrated Charging
Unit and Hybrid Energy Storage System. While designing robust nonlinear controllers,
the task of devising resilient nonlinear controllers presents a notable challenge due to
factors including, but not limited to, actuator limitations and saturation effects. A con trol design investigation is conducted employing nonlinear dynamic inversion, effectively
mitigating the necessity for complete state feedback. The designed system is subjected
to in-depth scrutiny through nonlinear simulations. The simulation outcomes vividly
demonstrate the successful pursuit of desired command tracking when the formulated
controller is employed within the comprehensive system framework. Classical stabil ity margin analysis is harnessed to strategically attain the desired equilibrium between
robust stability and optimal disturbance rejection. The findings strongly suggest the
viability of implementing dynamic inversion in the context of PHEV control design,
contingent upon the application of comprehensive full-order linear analysis to ensure
overall stability and accurate modeling of low-frequency dynamics. The obtained re sults are subsequently juxtaposed with outcomes derived from the utilization of Integral
Backstepping (IBS) control.
