An electric drive system has a power source and a generator operatively
connected to the power source. The electric drive system also has at
least one energy storage device such as a capacitor configured to store a
supply of power. The electric drive system further has a common bus
configured to direct the power output to the capacitor. The electric
drive system also has at least one motor configured to receive power from
the common bus. A controller for the electric drive system is provided,
having an article therewith having a computer readable medium with a
control algorithm recorded thereon. The control algorithm includes means
for compensating for a change in power demand on a DC bus of the electric
drive system.
