摘要

A robust variance controller based on disturbance estimation is proposed for bank-to-turn (BTT) missile attitude control with the characteristics of nonlinearity and disturbances. The nonlinearity and uncertainty in attitude motion are considered as the total disturbance which is estimated by the designed nonlinear disturbance observer. The estimated value of the disturbance is introduced into the control system for compensation. The observation error of the disturbance observer is introduced into the linear attitude motion model of the BTT missile as the new disturbance input. Then a linear feedback controller is designed by the robust variance control theory. The controller configures the closed-loop poles in a specific disc area while maintaining the steady-state variance of the state variables within a given range, which ensures good dynamic and steady-state characteristics of the system. The simulation results show that the robust variance attitude controller proposed guarantees good control performance and robustness in the presence of uncertainties.
