| Abstract: | The air rudder electromechanical servo system plays a crucial role in ensuring the safe and efficient operation of the aircraft. However, the immeasurable command output and the mismatched channel between input and unknown disturbance bring great challenges to its controller design. To tackle this issue, this study proposes a disturbance compensation‐based feedback linearization servo control strategy. This approach uses a radial basis function neural network‐based nonlinear observer to estimate the immeasurable command output and disturbance. Subsequently, a feedback linearization control algorithm is employed using these estimations to achieve disturbance compensation for the air rudder electromechanical system. Following the Lyapunov stability theorem, it is proved that the stability of the electromechanical servo system under the designed control algorithm can be guaranteed. At last, extensive simulation results are provided to demonstrate the effectiveness of the proposed control approach. [ABSTRACT FROM AUTHOR] |
