Elevator Motoring and Regenerating Dynamic Gain Compensation Abstract A polyphase induction motor propels an elevator car. The motor is powered by a multiphase inverter which receives power from a battery. The inverter is controlled in such a way as to control the fre- quency and amplitude of the power supplied to the motor in order to control the motor's speed, acceler- ation, and slip. That inverter control is accomplished by sensing the motor's speed and in response providing predetermined slip and torque signals. The slip can be controlled over a range which can provide negative slip, by which power is regenerated into the battery, which is thereby charged, and positive slip for motor- ing torque. A charger also charges the battery. The motor and its controls are thereby ostensibly isolated from the power system that supplies power to the charger, the battery handling the peak power require ments. Thus, little noise is injected into the power system. Speed loop gain is adjusted depending upon whether the motor is motoring or regenerating. This motor control system is thus efficient to operate, economical to build and very quiet.
