State Observer based Adaptive Fuzzy Backstepping Compensation Control of Passive Torque Simulator

Passive Torque Simulator (PTS) is an important ground based hardware tester simulator used for qualification of flight actuation system under aerodynamics torque loading .In this work extra torque disturbance due to actuator motion under test is analyzed and fuzzy Backstepping control with online parameters tuning scheme is proposed. Since extra torque affects both transient and steady state performance of the control loop, high gain adaptive control is investigated to improve the transient response of PTS torque tracking. Finally fuzzy Back stepping control with online parameters tuning scheme is proposed to improve torque tracking performance of load simulator both in transient and steady state. Simulations results show the validity of proposed control.

W artykule przedstawiono analizę wpływu ruchu siłownika w czasie testu, na zakłócenia pomiaru momentu obciążenia na potrzeby symulatora obciążenia aerodynamicznego w systemie siłowników (ang. Passive Torque Simulator). W algorytmie wykorzystano sterowanie oparte na logice rozmytej z krokiem wstecz i parametrami dobieranymi online.
