One such constraint is actuator saturation. Also in many mechanical systems, the tracking control is one of the most important problems. Therefore in the unstable system in which the actuator saturation exists, the domain of the initial states corresponding to an arbitrary reference signal, in which the tracking condition is achieved, should be considered. Such a tracking domain is generally complicated. In the paper, the approximate tracking domain is derived analytically with a simple numerical example.","PeriodicalId":137513,"journal":{"name":"Proceedings of the 38th IEEE Conference on Decision and Control (Cat.

A necessary condition of optimality in the form of a global maximum principle as well as a sufficient condition of optimality are presented. The general result is also applied to a backward linear-quadratic control problem and an optimal control is obtained explicitly as a feedback of the solution to a forward-backward equation. Finally, a nonlinear problem with additional integral constraints is discussed and it is shown that the duality gap is zero under the Slater condition.","PeriodicalId":137513,"journal":{"name":"Proceedings of the 38th IEEE Conference on Decision and Control (Cat.

When measured in dBs, the power loss follows a mean reverting Ornstein-Uhlenbeck process, which implies that the power loss is log-normally distributed. The arrival times of different paths are modeled using non-homogeneous Poisson counting processes and their statistical properties of the multipath power loss are examined. The moment generating function of the received signal is calculated and subsequently exploited to derive a central limit theorem, and the second-order statistics of the channel.","PeriodicalId":137513,"journal":{"name":"Proceedings of the 38th IEEE Conference on Decision and Control (Cat.

This paper summarizes a methodology developed by the author for the design of a daily target setting system over the past few years. The methodology realizes PULL-then-PUSH and proportional capacity allocation principles to meet production demands in a smooth way while maximizing machine utilization. As machine capacity allocation and available wafer flows are intertwined, the target setting problem can be viewed as a fixed-point iteration problem. A deterministic queueing analysis-based algorithm is designed to estimate cycle times and hence wafer flows. The methodology iterates between capacity allocation and cycle time estimation until a fixed-point capacity allocation is achieved.","PeriodicalId":137513,"journal":{"name":"Proceedings of the 38th IEEE Conference on Decision and Control (Cat.

The Nonlinear Autoregressive Moving Average model with eXogenous input (NARMAX) is shown to be able to represent a nonlinear stochastic dynamical system under certain conditions. As the dimension of the input space is finite, it can be readily applied in a practical application. It is well known that the training of recurrent networks using the gradient method has a slow convergence rate. In this paper, a fast training algorithm based on the Newton-Raphson method for a recurrent neurofuzzy network with NARMAX structure is presented. The convergence and the uniqueness of the proposed training algorithm are established. A simulation example involving a nonlinear dynamical system corrupted with the correlated noise and a sinusoidal disturbance is used to illustrate the performance of the proposed training algorithm.","PeriodicalId":137513,"journal":{"name":"Proceedings of the 38th IEEE Conference on Decision and Control (Cat.

In this article, the inherent limitations of such approaches are studied. Specifically, it is shown that such a transformation incurs additional dynamics which can be characterized by appropriate additional eigenvalues. The critical delay values when such additional eigenvalues cross the imaginary axis can be explicitly calculated. If the smallest of such delays is the smallest of the stability delay limit of the original system, then any stability criteria obtained using such transformation will be conservative.

The scheduling of a frozen-time, frozen-state controller for fast time-varying dynamics is known to be mathematically fallacious and practically hazardous. Therefore, recent research efforts are being directed towards applying time-varying controllers. In this paper, we introduce a differential algebraic eigenvalue theory for linear time-varying systems, and a novel decoupling and tracking control scheme is proposed by using the PD (parallel differential) eigenstructure assignment scheme via the differential Sylvester equation and a CGT (command generator tracker) for linear time-varying systems. The presented method is illustrated by numerical examples.","PeriodicalId":137513,"journal":{"name":"Proceedings of the 38th IEEE Conference on Decision and Control (Cat.
