Abstract
AbstractA feedback loop for a pair of Hydraulic Airbrake Actuators of an aircraft, controlled by Flight Control Computer (FCC) is designed and developed. The work involved is to analyze and design a control algorithm to achieve synchronized motion between two actuators. The FCC correlates the operational parameters to the position requested by the pilot and monitors the system during normal operation and under failure conditions. The desired motion is achieved through a closed loop feedback control system that senses the actual position of the actuators and corrects them until the desired position is reached. The control algorithm is tested against various test cases. Tests on Hydraulic air break actuators, driven by solenoid operated electro-selector valves and controlled by FCC, proved highly accurate in position regulation as compared to a conventional open loop control system.
