This paper is concerned with the non-fragile robust model predictive control(MPC) for a class of polytopic uncertain systems with packet dropouts.A novel system with respect to non-fragile controller and packet dropouts is investigated by MPC approach.A non-fragile controller is adopted with hope to deal with the controller perturbations and deviations,which might be a potential factor for system dynamic performance deterioration and ***,a sufficient stability criterion is presented by using stochastic analysis and Lyapunov-like function approach,meanwhile,the corresponding control law and the upper bound of the quadratic cost function are derived by solving an optimization subject to the convex ***,some simulation examples are employed to show the effectiveness of the method.

Motivated by the effort to understand the mathematical structure underlying the Teukolsky equations in a Kerr metric background, a homogeneous integral equation related to the prolate spheroidal function is studied. From the consideration of the Fredholm determinant of the integral equation, a family of generalized error function is defined, with which the Fredholm determinant of the sinc kernel is also evaluated. An analytic solution of a special ease of the fifth Painlev~ transcendent is then worked out explicitly.
By making full use of the curvature of the earth and ground clutter, the ultra-low altitude flight technique can significantly increase the difficulty of detecting and intercepting unmanned aerial vehicles (UAVs), and...
