The main results are the theorems which assure the overall stability of the closed-loop system, which are proved in a straight way compared with previous stability analysis results. Trial Software Product Updates. For robust stability of closed-loop discrete-time parametric systems, it is sufficient that. Anna Patete 1Katsuhisa Furuta 2.

Continuous Lyapunov equation solution – MATLAB lyap

The analysis is extended to the case where the system model is subject to system and measurement noises.


The controller design with the GMVC based on the sliding mode control concept, in the case of time-invariant systems [3, 6, 7], is reviewed fe this section.

Based on key technical lemmas, the global convergence of implicit self-tuning controllers was studied for discrete-time minimum phase linear systems in a seminal paper by Goodwin [4] funcones for explicit self-tuning controllers in the case of non-minimum phase systems by Goodwin [5].

Then, by using of the recursive equations 13 and 14 for a positive boundedis proved negative semi-definite, i.

Solution does not exist or is not unique. Using the definition of given in Eq. In the following, the proposed algorithm in Eq. Equation 25 yields Eq. This page has been translated by MathWorks.

The initial condition where I is the identity matrix and the parameter forgetting factor are chosen. Translated by Mouseover text to see original. Thus, and vanish as N approaches to infinity.

The self-tuning control based lyapunv GMVC algorithm presented is extended to the case where a forgetting factor is introduced into the recursive estimate equations 9 and 10 to deal with this type of time-varying systems. Retrieved from ” https: Generalized lyalunov variance control. Finally, by taking the expectation with respect to in 28Eq.

Lyapunov function

The matrices ABand C must have compatible dimensions but need not be square. The results have been extended to the case where system and measurement noises are considered into the system model. The paper is organized as follows: It has been proved [6, 7] that the following self-tuning algorithm assures the overall stability for SISO time invariant systems, when the system constant parameters are not accurately known, by the recursive estimation of the controller parameters andunder the following assumptions.


Wikipedia articles incorporating text from PlanetMath.

The A matrix is stable, and the Q matrix is positive definite. A similar concept appears in the theory of general state space Markov chainsusually under the name Foster—Lyapunov functions.

Clark [8] studied the stability of self-tuning controllers for time-invariant systems subject to noise, based on the idea of describing the system in a feedback lapunov and using the notion of dissipative-real systems.

The purpose of this paper is to analyze the stability of the implicit self-tuning controller for discrete time-varying systems TVS and discrete time-varying systems subject to system and measurement noises.
