Adaptive block dynamic surface control of BTT missiles

This paper proposes a novel adaptive block dynamic surface control algorithm for BTT missiles. The control system model of BTT missiles is reconstructed into the block strict-feedback form with matched and unmatched uncertainties. Under the assumption that the uncertainties are norm-bounded, an adaptive block dynamic surface control algorithm is proposed for such a time-varying nonlinear systems. It is proved that the attitude angles can be driven to track the desired trajectory with expected precision and all the states are kept bounded simultaneously by choosing proper design parameters. The simulation results show the effectiveness of the proposed method.
