A Robust Integrated Guidance and Control Approach for the Missile with Swing Nozzle

In this paper, in order to enhance the cooperative relationship between guidance subsystem and control subsystem of the missile with swing nozzle, a modeling and design approach facing to integrated guidance and control is proposed in full meaning. First, according to the missile plant with swing nozzle, a state-dependent linear state-space model is established facing to integrated guidance and control design. Based on this model, an integrated guidance and control algorithm, including a basic feedback control algorithm and a robustness-enhanced control algorithm, is proposed to ensure the fast convergence of system states in the existence of unmatched uncertain dynamics. Simulation results present that, the proposed integrated guidance and control algorithm can realize accurate tracking and stable control of the chosen missile, and satisfy the process restriction conditions. Moreover, it also possesses the robust property against model uncertainties.
