摘要：In this paper, a disturbance observer based optimal attitude control scheme using θ − method is presented for the near space vehicle (NSV). Firstly, θ − method is used to design the optimal controller for the nominal system without considering the disturbance. Secondly, nonlinear disturbance observer (NDO) technique is applied to estimate the disturbance and the estimation result can be used as the disturbance compensation term. Then, the composite controller consisting of optimal controller and disturbance compensation term is proposed. The closed-loop system signals are proved to be uniformly ultimately bounded (UUB) using Lyapunov method. Finally, simulation results show the effectiveness of proposed control scheme. © Springer International Publishing AG 2017.
