CONTROL SYSTEM AND METHOD FOR TRANSITIONING BETWEEN POSITION CONTROL AND FORCE CONTROL FOR MULTI-STAGE TURBO ENGINE TURBINE BYPASS VALVE

摘要

A control system comprising a current control module and a force control module. The current control module selectively supplies a current to a turbine bypass valve (TBV) to adjust the TBV to a predetermined position. The force control module selectively adjusts the current in response to a determination that an actual TBV position is less than a predetermined distance from the predetermined position.
