Abstract:
Systems and methods for controlling a permanent magnet synchronous motor to eliminate the need to filter a PWM output of the motor's drive system. In one embodiment, the motor's drive transforms measured output currents to a d-q reference frame and uses these to determine demanded Vd and Vq voltages. An inverter angle is determined from the difference between the demanded Vd and Vq voltages. A demanded bus voltage is determined as the square root of the sum of the square of the demanded Vq and the demanded Vd, multiplied by 2/pi. An inverter angle is determined as the arctangent of (−demanded Vd/demanded Vq). The demanded and actual bus voltages are used to determine a firing angle for the converter. The controller uses this information to generate a six-step waveform that can be provided to the motor without requiring output filtering.

Claim (Index 3):
The electric submersible pump system of  claim 1 , wherein the controller includes a first proportional integral controller that determines the Iq reference value, a second proportional integral controller that determines the demanded Vd voltage in dependence on the difference between the Id current and the Id reference value, and a third proportional integral controller that determines the demanded Vq voltage in dependence on the difference between the Iq current and the Iq reference value.
