Sliding mode control is a typical nonlinear control strategy which was easy realized and with strong robustness, in this paper, a neuro sliding mode controller was designed with RBF neural networks and the stability of the proposed control scheme is proved by Lyapnouv theorem. For the chattering of sliding mode control are often derive from switching gain, the gain was adjusted with neural networks...
An optimal guidance method using the range as an independent variable for the reentry maneuverable spacecraft is presented in this paper. Firstly, the aerodynamic coefficients are estimated by using the strong tracking filter (STF). Then, the linear deviation equations are formulated by linearising the original nonlinear equations of motion around the nominal trajectory. Finally, the optimal linear...
Allowing for simultaneous occurrence of multiple actuator faults in signal channels, the problem of robust reliable tracking controller design for a class of uncertain systems with polytopic type uncertainty is investigated. Based an unstructured quadratic separator, a less conservative condition for the existence of a reliable tracking control is derived. In order to reduce the design conservatism,...
