Description
Summary:This paper concerns high-accuracy roll control for single moving-mass controlled reentry vehicle. Considering the simultaneous existence of matched and mismatched uncertainties in the reentry vehicle system, a continuous integral robust control strategy is proposed based on the backstepping design framework. The controller uses the error transformation method to transfer the mismatched modeling uncertainty to the control input channel, and then a robust structure constructed in the controller can handle it together with the matched modeling uncertainty. The final control input is continuously differentiable, which is benefit for tracking performance improvement and practical controller implementation. The proposed controller theoretically guarantees asymptotic tracking performance via Lyapunov analysis. Finally, simulation results are given to illustrate the efficiency of the proposed approach.
