论文摘要: An adaptive control method for a class of uncertain linear time varying (LTV) systems from the
perspective of differential algebraic framework is proposed. A novel algorithm of numerical differentiator is used for the states reconstruction and the estimation of the generalized disturbance. Based on the pole assignment technique and H robust control theory, a hybrid adaptive control law is derived for accommodating system uncertainties, disturbances and measurement noises. By using Lyapunov’s direct and indirect methods, the stability and the performance are discussed. The pitch control of launch vehicle is taken as an illustrative example to validate the efficiency of the proposed control method.
