Recibido el 8 de Diciembre de Retrieved from ” https: The time difference of Eq. The third and fourth terms in the right-hand side of Eq.

Views Read Edit View history. As shown, does not intersect with the critical circlewhich implies that the sufficient condition for robust stability is satisfied. Figure 2 shows the output responses when, after samples, the system model in Eq. ce

The A matrix is stable, and the Q matrix is positive definite. The uncertainty in system characteristics leads to a certain family of models rather than to a single system model to be considered.

Using the recursive equations 13 and 14 into 23for the lyapunlv relation is obtained. References [1] Bartels, R.

### Continuous Lyapunov equation solution – MATLAB lyap

Equation 31 implies that approaches to zero as N goes to infinity; then the left-hand side of Eq. The representation of the llyapunov system with input and output is given by: 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.

Then, for a large N the following relation is derived: Description lyap solves the special and general forms of the Lyapunov equation. This model is so-called AR Auto Lyyapunov model. From the third term on the right-hand side of Eq. Since the polynomial is designed to satisfy Eq.

Self-tuning control of time-varying systems based on GMVC. Select a Web Site Choose a web site to get translated content where available and see local events and offers. For robust stability of closed-loop discrete-time parametric systems, it is sufficient that. The parameters of the control law for the real lyapumov with unknown parameters are estimated using a recursive least-squares RLS algorithm.

For certain classes of ODEs, the existence of Lyapunov functions is a necessary and sufficient condition lyapunv stability.

The idea is similar to the discrete-time sliding mode control [3]. However, all these researches have been done for time-invariant systems TIS. Other MathWorks country sites are not optimized for visits from your location.

Maracaibo Zulia A-Venezuela retecin luz. The candidate Lyapunov function is given by: The necessary and sufficient condition for the control input to make stable is that all the roots of the polynomial: All Examples Functions Blocks Apps.

## Lyapunov function

By the chain rule, for any function, H: Given a positive definite matrixa parameter and an initial parameters vectorif the estimate of the controller in Eq.

CORIAN 809 SINK PDF

The principal contribution of the obtained stability results is to assure the overall stability if the presented control algorithm is implemented on a real system with time-varying parameters, even in the presence of system funckones measurement noises.

The degree of polynomial iswhich implies that depends only on future states of x. The converse is also true, and was proved by J.

Stability of implicit self-tuning controllers for time-varying systems based on Lyapunov function. Wikipedia articles incorporating text from PlanetMath. Simulation examples are given in section 4. The most recent data is given unit weight, but data that is t time units old is weighted by.
