Abstract

The three channel control model with uncertainty parameters, structural damage disturbance and observation noise for asymmetric wrap-around fin rolling missiles is established according to the movement characteristic. An improved trajectory linearization control (TLC) method based on Lipschitz adaptive observer is proposed. The controller is derived by the time-scale separation principle. The Lipschitz nonlinear state observer is systematically obtained by solving the linear matrix inequality approach. The damage disturbance model of fin is established and the parameters are estimated. The compensation control law based on the estimated parameters and state feedback improves the TLC method. Simulation experiments show that the improved method can make the missile attitude motion track control command accurately, and the robustness and accuracy of missile attitude control are ensured under the condition of the system parameters uncertainty, observation noise and the random suddenly unknown disturbance.
