This paper addresses the design of flight control system related to neural network-based adaptive dynamic surface control for the longitudinal motion of an airbreathing hypersonic vehicle. The control objective is to provide adaptive velocity and altitude tracking in the presence of the model uncertainties and unknown nonlinearities caused by changes of flight conditions. By approximating the unknown...
The design of eigenstructure assignment in second-order dynamic systems via proportional-integral-derivative (PID) feedback is considered. Based on a group of parametric solutions to a type of generalized Sylvester matrix equations, a complete parametric method for the proposed eigenstructure assignment problem is presented. This method gives simple complete parametric expressions for the PID feedback...
The exponential stability of nonlinear Ito differential systems with Markovian switching is studied. According to the theory of stability of stochastic systems and Ito differential formula, by choosing proper stochastic Lyapunov function, applying generalized Ito formula, some sufficient conditions of exponential stability of such system was obtained, which improved existed results, with less conversations.
This paper is concerned with the problem of full-order robust L2-Linfin estimation for continuous-time polytopic uncertain time-delay systems. An improved L2-Linfin performance criterion is provided in terms of linear matrix inequalities. It exhibits a kind of decoupling between the Lyapunov matrices and the system dynamic matrices compared with the existing result. Then two sufficient conditions...
