Near synchronous controlled induction motor drive actuation system

摘要

A distributed electromechanical actuation system including multiple electromechanical actuators intended to operate together in a synchronous (or near synchronous) manner. Each individual actuator is powered by one or more induction motors or other appropriate motor such as a stepper motor. The induction motors are designed to have a very high pullout torque with very low slippage to the pull out point. The group of actuators is controlled from a single controller (e.g., an induction motor controller) that utilizes a Volts per Hertz type of open loop control where the bus voltage and frequency are controlled to assure that the motors always operate on the low slip side of the pull out point performance curve.

主权项

1. A control system for controlling a plurality of actuators, the system comprising:
a plurality of actuators for actuating movement of one or more adjustable components of an aircraft, wherein each actuator has a first end coupled to a structure of the aircraft and a second end coupled to one of the one or more adjustable components and each actuator additionally includes a motion control assembly that includes a drive path from a motion provider to the one adjustable component, wherein the one or more components is configured to move along a respective drive path; and a single power module controller operable to simultaneously output motor drive power from a single power module through a common electrical bus to at least two of the plurality of the motion providers in a synchronous manner to actuate movement of the one or more adjustable components.
