To improve the development efficiency, RF guided HILS system is adopted to examine the missile system. To ensure the effectiveness of the simulation result, it is necessary to evaluate the reliability of the RF guided HILS system. Because of some factors such as measurement error and method error, evaluation index values tend to have uncertainty. In this context, the reliability evaluation index system...
This paper investigates a novel control strategy for the position and attitude tracking control problem of a quadrotor UAV based on terminal sliding mode control. To realize the control objective, the model of the quadrotor UAV with six degrees of freedom which is actually a class of underactuated systems, is reasonably divided into a fully actuated subsystem with two degrees of freedom and an underactuated...
The attitude control is the key of the automatic flight for a quad-rotor aircraft. In order to guarantee the robustness of the quad-rotor aircraft for various uncertainties, a new design method of the robust optimal control that integrates the sliding mode control theory with state-dependent Riccati equation (SDRE) is proposed in this paper. First, the whole attitude kinematical model is obtained...
This paper investigates the hybrid projective synchronization problem between different fractional-order chaotic systems in the presence of system parameter uncertainty and unknown bounded external disturbances. By means of both the stability theory of fractional order differential system and adaptive control method, a novel robust controller and updating laws have been designed for achieving hybrid...
A nonlinear robust adaptive backstepping attitude controller is designed for a reusable launch vehicle in reentry phase under input constraint, model uncertainty and external disturbance. for the couplings between the translational and rotational motions, a control-oriented model (COM) with uncertainty is firstly derived to succinctly design controller. It is worth pointing out that the uncertain...
In this paper, H∞ filtering problem for a class of nonlinear uncertain discrete-time singular Markov jump systems with time-varying delay is discussed. The nonlinear function satisfies a quadratic constraint. First, a sufficient condition is given that the nominal filtering error system is regular, causal, has unique solution in a neighborhood of the equilibrium point, is stochastically stable and...
