Adaptive bounding techniques for stable neural control systems
(IEEE, 1995)This paper considers the design of stable adaptive neural controllers for uncertain nonlinear dynamical systems with unknown nonlinearities. The Lyapunov synthesis approach is used to develop state-feedback adaptive control ...

Adaptive congestion control in ATM based networks: Quality of service and high utilisation
(1997)To improve network utilisation and robustness for Asynchronous Transfer Mode (ATM) networks there is increasing evidence that reactive congestion controls are necessary. However the large bandwidth-delay product and the ...

Congestion control in differentiated services networks using fuzzy logic
(2004)The provision of quality of service (QoS) in a differentiated services (Diff-Serv) environment requires an adequate differentiation between high-priority/assured and low-priority/best-effort classes of service in the ...

Examples of optimal control for nonlinear stochastic control problems with partial information
(IEEE, 1995)Partially observable stochastic optimal control problems are considered. It is shown, via an information state approach and dynamic programming, that several classes of nonlinear systems with non-linearities in the dynamics ...

Feedback control utilizing packet dropping network links
(2002)The increasing availability of network connectivity has prompted the study of computer-based control methodologies that are implemented centrally or distributively using existing network infrastructure as the communications ...

Finite-dimensional nonlinear output feedback dynamic games and bounds for sector nonlinearities
(1999)In general, nonlinear output feedback dynamic games are infinite-dimensional. This paper treats a class of minimax games when the nonlinearities enter the dynamics of the unobservable states. An information state approach ...

A heuristic search algorithm for maneuvering of UAVs across dense thermal areas
(2007)In order to ensure that an aircraft has the potential to meet the assigned performance requirements which are often mission specific, the particular aerodynamic demands involved must be taken into account during the aircraft ...

Information Transfer of Control Strategies: Dualities of Stochastic Optimal Control Theory and Feedback Capacity of Information Theory
(2017)The control-coding capacity of stochastic control systems is introduced, and its operational meaning is established using randomized control strategies, which simultaneously control output processes encode information, and ...

Joint preprocessing and feedback strategies for perfectly reconstructing equalizers
(2008)In this paper we consider the transmission of discrete-valued data via a communication channel that is subject to (additive) noise with a known upper bound on its magnitude but otherwise completely unrestricted and unknown ...

Low-threshold lasers based on a high-mobility semiconducting polymer
(2006)Progress toward electrically driven conjugated polymer lasers should benefit from the identification of materials that exhibit good charge transport properties coupled with large optical gain. Here, we report a detailed ...

MIMO disturbance and plant uncertainty attenuation by feedback
(2002)This paper investigates the ability of feedback to reduce plant and disturbance uncertainties in the MIMO case, by solving two fundamental problems posed by Zames in the late seventies. The approach used here is Banach ...

Neural network control of unknown systems
(IEEE, 1998)In this paper, we show that for all unknown Multi-Input (MI) nonlinear system that affected by external disturbances, it is possible to construct a semi-global state-feedback stabilizer when the only information about the ...

Non-identifier based adaptive control scheme with guaranteed stability
(2006)In this paper, we investigate a non-identifier based adaptive control scheme for single-input single-output (SISO) plants. The overall adaptive control system can be viewed as a feedback interconnection of a SISO plant, a ...

Novel Matrix Singular Value Inequalities and Their Applications to Uncertain MIMO Channels
(2015)Novel matrix singular value inequalities are established for a sum/product of three matrices. Their application to the uncertain (compound) multiple-input multiple-output (MIMO) channel subject to normed additive uncertainty ...
