Abstract :
An adaptive block dynamic surface control algorithm is proposed for BTT missiles in presence of input saturations. An auxiliary system is introduced, and then the overall system consisting of the auxiliary system and the control system model of the missile is reconstructed into the block strict-feedback form with matched and unmatched uncertainties. By introducing a set of well defined smooth functions to approximate the saturation functions, an adaptive block dynamic surface control algorithm is proposed for this nonlinear system. It is proved that the attitude angles can be driven to track the command signals 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.
