This paper addresses fault detection and fault isolation in single-type torque-summed architecture. The analysis is based around a 4-lane actuation system capable of driving aerodynamic and inertial loads (with 2 lanes failed) of an aileron control surface similar to that of the Sea Harrier. The paper describes the lanes and the dedicated embed microprocessor/s that performs the control and monitoring...
High integrity in multi-lane smart electromechanical actuation systems is achieved through hardware redundancy and intelligent monitoring. The main aim of this paper is to address cross-monitoring in single-type torque-summed architecture. The paper will consider hardware cross-monitoring, in three-phase equivalents that represent the brushless dc motor in this architecture, hence allowing for detailed...
