ROBUST CONTROL ALGORITHM FOR PMSM MOTOR WITH HALL POSITION SENSORS

Abstract eng:
The paper deals with a development of robust control algorithm for electro-mechanical actuator, which is intended to delivery of fuel to Auxiliary Power Unit APU in an aircraft. Contemporary technological developments within the all-electric aircraft concept lead to replacement of existing hydraulicmechanical circuits by intelligent actuators based on electrical servo drives which increase overall reliability and utility value, decrease operating costs, dimensions and weight. The aims of the development were to design a model of control algorithm for Electrically Driven Fuel Pump EDFP in accordance with rigid aviation standards and to verify this algorithm on a test bench that simulates a real fuel circuit. A Permanent Magnet Synchronous Motor PMSM is used as actuator and low-cost Hall position sensors are selected for sensing rotor position.
