| Summary: | In-wheel-motor drive electric vehicle (EV) is an innovative configuration of
the modern EV, in which each wheel is driven individually by an electric
motor. The classical traction motor control called the Independent Machine
Control Structure (IMCS) using a PID speed controller presents major
inconveniences in modern EV safety, when the proposed control can not ensure
stability of the EV with differing road topology and variations of speed. A
new approach is proposed for a control of a two-in-wheel-motor drive EV,
called the Maximum Control Structure MCS. This is based on a multivariable
PID (MIMO-PID) strategy, which is employed to estimate the linear speed error
of each of the two back driving wheels, when the error of each wheel is taken
into account in the other speed control computations. Simulation results show
that the new control system presents increased safety for the EVs compared
with the IMCS strategy and can maintain the error slip rate within the
optimal range, ensuring the stability of the vehicle either in a straight or
a curved line. |
