This paper addresses closed-loop stability analysis of PID controlled local model networks. The proposed method allows to investigate exponential or asymptotic stability of the closed-loop system. For this purpose a common quadratic Lyapunov function is used as stability criterion. Due to the fact that the Lyapunov approach requires a state-space model a suitable closed-loop state-space system ...

A direct adaptive nonlinear control framework for multivariable nonlinear uncertain systems with exogenous L2 disturbances is developed. The proposed framework is Lyapunov-based and guarantees partial asymptotic stability of the closed-loop system; that is, asymptotic stability with respect to part of the closed-loop system states associated with the plant, as well as a nonexpansivity constrain...

high-precision three-axis attitude control scheme is vitally important to deal with the overactuated spacecraft, as long as the overall performance through rapid response can be in general acquired. due to the fact that the rigid-flexible spacecraft is somehow applicable, in so many academic and real environments, there is a consensus among experts of this field that the new insights in develop...

remanufacturing is an industrial process that makes used products reusable. remanufacturing is a way to establish a closed-loop supply chain. one of the important aspects in both reverse logistics and remanufacturing is pricing of returned and remanufactured products (called cores) that it has been noticed in this paper. in addition, in this paper the researchers have tried to present a mathema...

this paper introduces a technique for controlling a class of uncertain chaotic systems using an adaptive fuzzy proportional-integrator-derivative (pid) controller with h∞ tracking performance. the purpose of this work is to achieve optimal tracking performance of the controller using backtracking search algorithm (bsa). bsa, which is a novel heuristic algorithm, has an easy structure with singl...

One of the main drawbacks while implementing the interaction between a plant and a supervisor, synthesised by the supervisory control theory of Ramadge and Wonham, is the inexact synchronisation. Balemi was the first to consider this problem, and the solutions given in his PhD thesis were in the domain of automata theory. Our goal is to address the issue of inexact synchronisation in a process ...

In this report, we propose a periodic state feedback control law for a class of continuous-time linear periodic systems. The proposed control law generates a sufficiently high frequency sinusoidal in the coefficient of a closed loop system, then the closed loop system is shown to be exponentially stable based on the averaging method. It is also shown that a closed loop solution is approximated ...

A family of algorithms for the identification of continuous-time nonlinear plants operating in closed loop is presented. An adjustable closed-loop output error-type predictor parameterized in terms of the existing controller and the estimated plant model is used. The algorithms are derived from stability considerations in the absence of noise and assuming that the plant model is in the model se...

This note presents a method for synthesizing a static state feedback controller for multiple-input linear systems over discrete sets. The method allows of a complete setting of the cyclic subspaces of the closed loop system by specifying invariant polynomials of the closed loop system. To this end, fundamentals of finite field theory and basic elements of the polynomial approach are developed t...

A controlled Lagrangian approach is presented for the stabilization of an inverted pendulum mounted on a cart. The stabilization strategy consists in forcing the closed-loop system to behave as an Euler-Lagrange system, with a fixed inertia matrix. For carrying it out, it is necessary to adequately shape the potential and kinetic energies of the closed-loop system. The idea behind this procedur...
