This paper describes a design of a composite control system based on model predictive control (MPC) for unmanned airship. Weight coefficient adjustment strategy of control variable and state variable of the predictive controller is also presented in this paper. The nonlinear simulation of the composite control system shows that the desired performance(More)
This paper is concerned with the problem of exponential stability for a class of stochastic neural networks with Markovian switching and mode-dependent interval time-varying delays. A novel Lyapunov-Krasovskii functional is introduced with the idea of delay-partitioning, and a new exponential stability criterion is derived based on the new functional and(More)
For the improvement of accuracy and better fault-tolerant performance, a global position system (GPS)/vision navigation (VISNAV) integrated relative navigation and attitude determination approach is presented for ultra-close spacecraft formation flying. Onboard GPS and VISNAV system are adopted and a federal Kalman filter architecture is used for the total(More)
This paper deals with the investigation of the impact of relative navigation error on relative semimajor axis (SMA) estimation for formation flying of spacecraft in high earth orbit (HEO). The use of carrier-phase/code-phase differential Global Positioning System(GPS) measurements in relative navigation filters is analyzed, with a particular augmentation of(More)
