This paper considers the nonlinear H1 control problem for systems subject to delayed measurements. Necessary and su cient conditions for the solvability of the problem are presented. A key point of our approach is the extension of the information state concept. In particular, the information state is no longer the \worst case cost to come" function. We also present the certainty equivalence pri...

Welcome to the Special Issue on New Advances in H∞ Control and Filtering for Nonlinear Systems. While the H∞ control and filtering theory for linear systems was well established since the early 1990s, the H∞ methods for nonlinear systems are still being actively developed varying from rigorous substantiation of nonlinear H∞ approach to technical design of advanced H∞ algorithms for special clas...

introduction this paper proposes the concept of autonomous drug-encapsulated nanoparticle (adenp) as a novel non-invasive approach to prevent atherosclerosis. adenp consists of three simple units of sensor, controller (computing), and actuator. the hardware complexity of adenp is much lower than most of the nanorobots, while the performance is maintained by the synergism in the swarm architectu...

This paper applies the nonlinear H∞ control theory to helicopter hovering manuver whose complete six degree-offreedom nonlinear equations of motion with coupled rotor and inflow dynamics are considered directly without linearization. Under this approach, the exact nonlinear equations governing both the longitudinal and lateral motions are considered. The control surface inverse algorithm (CSIA)...
