    Abstract

    According to the characteristics of nonlinear and multiple jammers for the aerial photography stabilized platform, an active disturbance rejection detached robust control method is developed. The dynamic equations of the three-axis stabilized platform were deduced based on the Lagrange theorem. Multiple parallel extended state observers were designed for estimation of unknown dynamics and external disturbance of each freedom, and the estimated states were used for nonlinear feedback control and compensation to improve system performance. The simulation and test results demonstrate the ADRVC has good adaptability and robustness to external disturbance and unknown variation. The designed controller not only satisfies the steady accuracy demands, but also effectively resists to the change of the inter and external disturbance. The experimental results show that Active Disturbance Rejection Controller has stronger robustness and adaptability, and demonstrate the feasibility and effectiveness of proposed method.
