Decoupled control of rotor torque and rotor electrical power delivered in a salient-pole, synchronous machine

Abstract

A drive system with a control algorithm that provides independent control of rotor torque and rotor electric power is described in this paper. One electromechanical machine is used for two purposes, viz., firstly to provide electromagnetic torque to rotate a rotor mounted load and secondly to provide electric power to equipment mounted on the rotor. The technique eliminates the need for slip rings. Simulation and practical results verifying the analysis are given. The system has applications such as rotational antennas and turret systems.
