Induction motor load compensation for power steering applications |
摘要 |
An induction motor control system for use in a power steering system, comprising: a power steering induction motor coupled to a power supply and providing motive input to pressurize a hydraulic steering subsystem; a phase current sensor for sensing the phase current output by the power supply; and a power steering controller coupled to the power supply for processing a commanded frequency input, the sensed phase current, and data contained in a plurality of software lookup tables using a transfer function to adjust the motor voltage produced by the power supply to control the speed of the power steering motor.
