Adaptive Electric Loading System Design in Aircraft Hardware-in-the-loop Simulation

For simulating accurately the aerodynamic hinge moment of aircraft control surface in the aircraft hardware-in-the-loop simulation,an adaptive electric loading system was designed by constructing the adaptive feedforward controller,considering the influence of the extraneous torque aroused from actuator motion.The convergence of the tracking error was proved by constructing proper Lyapunov function,based on the model reference adaptive control(MRAC).The simulation results indicate that the extraneous torque can be eliminated effectively,and the adaptive electric loading system may get high tracking performance.
