TL;DR: In this paper, an optimal control scheme for a class of nonlinear systems with time delays in both state and control variables with respect to a quadratic performance index function is proposed using a new iterative adaptive dynamic programming (ADP) algorithm.

TL;DR: In this article, the authors extend and improve the existing result on fault-tolerant control (FTC) of dynamic systems with actuator failures and external disturbances in several aspects, and the resultant control algorithms are faultindependent in that there is no need for explicit fault information in terms of its magnitude (size), or time instance of the fault occurrence, thus, is more user-friendly for control design and more feasible for implementation as compared with the existing work.

TL;DR: In this paper, a robust control approach is proposed to solve the stabilization problem for networked control systems (NCSs) with short time-varying delays, where the closed-loop NCS is described as a discrete-time linear uncertain system model, and the uncertain part reflects the effect of the variation nature of the network induced delays on the system dynamics.

TL;DR: In this paper, a simplified stability criterion is derived after establishing equivalence among several recently proposed stability criteria, and a new stability criterion which is much less conservative than the existing ones is presented.

TL;DR: In this paper, a fault detection and diagnosis approach based on multiblock kernel principal component analysis (MBKPCA) is proposed to monitor large-scale processes, in particular, definitions of nonlinear block contributions to T 2 and the squared prediction error (SPE) statistics are first proposed in order to diagnose nonlinear faults.

TL;DR: In this article, the population control problem associated with the equilibrium states of mixed-state quantum systems by using a Lyapunov function with degrees of freedom was studied, and the control laws were designed by ensuring the monotonicity of the Lyapounov function; main results on the largest invariant set in the sense of LaSalle are given.

TL;DR: In this paper, the stability of a class of linear neutral systems with time-varying delays is studied, where delay in a neutral-type term includes a fast-variate case (i.e., the derivative of delay is more than one), which has never been considered in current literature.

TL;DR: In this article, the authors proposed an adaptive localization approach for wireless sensor networks based on Gauss-Markov mobility model, which combines the perpendicular bisector strategy, the virtual repulsive strategy, and the velocity adjustment strategy to enhance localization efficiency.

TL;DR: In this paper, a stability analysis of the iterative learning control (ILC) problem for continuous-time systems with multiple state delays is presented, especially when system parameters are subject to polytopic-type uncertainties.

TL;DR: In this article, a delay-range-dependent condition is given which ensures that the nominal system is regular, impulse free, and mean-square exponentially stable in terms of linear matrix inequality.

TL;DR: In this paper, the linear-quadratic optimal control by dynamic compensation for rectangular descriptor system is considered, and a dynamic compensator with a proper dynamic order is given such that the closed-loop system is regular, impulse-free, and stable (called admissible), and its associated matrix inequality and Lyapunov equation have a solution.
