this paper investigates the problem of robust H-infinity and l(2)-l(infinity) filtering for a class of uncertain nonlinear discrete-time systems with multiple state delays. It is assumed that the parameter uncertainties appearing in all the system matrices reside in a polytope and the nonlinearities entering into boththe state and measurement equations satisfy global Lipschitz conditions. Attention is focused on the design of robust full-order and reduced-order filters guaranteeing a prescribed noise attenuation level in an H-infinity or l(2)-/l(infinity) sense with respect to all energy-bounded noise disturbances for all admissible uncertainties and time delays. Sufficient conditions for the existence of such filters are formulated in terms of a couple of linear matrix inequalities (LMIs), upon which admissible filters can be obtained from the solution of convex optimization problems. A numerical example is presented to illustrate the feasibility of the developed filter design methods.

this paper presents a new visual servoing scheme which is invariant to changes in camera-intrinsic Parameters. Current visual servoing techniques are based on the learning of a reference image withthe same camera used during the servoing. Withthe new method, it is possible to position a camera (with eventually varying intrinsic parameters), with respect to a non-planar object, given a "reference image" taken with a completely different camera. the necessary and sufficient conditions for the local asymptotic stability show that the control law is robust in the presence of large calibration errors. Local stability implies that the system can accurately track a path in the invariant space. the path can be chosen such that the camera follows a straight line in the Cartesian space. Simple sufficient conditions are given in order to keep the tracking error bounded. this promising approach has been successfully tested with an eye-in-hand robotic system.
