A new power regulator controller with multipleaccess
PID compensator is proposed, which can achieve a minimum memory
requirement for fully table lookup. The proposed regulator controller
employs hysteresis comparators, an error process unit (EPU) for
voltage regulation, a multipleaccess PID compensator and a lowpower
consumption digital PWM (DPWM). Based on the multipleaccess
mechanism, the proposed controller can alleviate the penalty of
large amount of memory employed for fully table lookup based PID
compensator in the applications of power regulation. The proposed
controller has been validated with simulation results.
