Lyapunov-Based Robustness Analysis Techniques for Clearance
2012This chapter considers different techniques for robustness analysis of uncertain systems modeled by linear fractional representations, based on the use of parameter-dependent Lyapunov functions and multipliers. Several sufficient conditions for robust stability, relying on the choice of simplified structures for the Lyapunov function and the multiplier

Lyapunov-Based Model Predictive Control
2011In Chap. 2, some basic results on Lyapunov-based control, model predictive control and Lyapunov-based model predictive control of nonlinear systems are first reviewed and then two Lyapunov-based model predictive control (LMPC) designs for systems subject to data losses and time-varying measurement delays are presented.

Thermodynamic approach for Lyapunov based control
IFAC Proceedings Volumes, 2009Abstract Abstract This paper focuses on non linear control of non isothermal Continuous Stirred Tank Reactors (CSTRs). The model of the CSTR is thermodynamically consistent in order to apply the control strategy based on the concavity of the entropy function and the use of thermodynamic availability as Lyapunov function.

Decentralised Lyapunov-based power system stabiliser
DRPT2000. International Conference on Electric Utility Deregulation and Restructuring and Power Technologies. Proceedings (Cat. No.00EX382), 2002This paper describes a new structure for a stability-enhancing excitation controller designed using a nonlinear multimachine system model and Lyapunov's direct method. The controller is shown to be robust, as the damping it introduces into the system is insensitive to changes in both the system topology/parameters and the pattern of network flows. Each

Lyapunov based control using contact structures
IFAC Proceedings Volumes, 2011Abstract By using the framework of contact systems and thermodynamics it is possible to state the problem of matching an open-loop and a target vector field in an augmented space, where extensive and intensive variables can be seen as independent variables. This simplifies the partial differential equation associated to the solution of the problem and

Lyapunov based Estimator for Buck Converter
2018 Electrical Power, Electronics, Communications, Controls and Informatics Seminar (EECCIS), 2018DC-DC converter plays an important role in the distribution of electricity in some applications. The most common type of DC-DC converter is buck converter. Failure in any components of buck converter can cause the performance of this equipment being degraded or even be fatal in some applications. The cause of failure is often encountered in the passive

Lyapunov-based stability region computation approach
2015 European Control Conference (ECC), 2015For the design of controllers, D-decomposition techniques like the Parameter Space Approach (PSA) are widely used to identify the space of stabilizing controller parameters. The PSA approach is based on sweeping over the entire range of singular frequencies which leads to an expensive numerical computation and a waste of time to obtain the boundaries ...

Stick-Slip Control: Lyapunov-Based Approach
2015Based on the neutral-type time-delay model of the drillstring torsional dynamics, this chapter addresses the design of stabilizing controllers aimed at eliminating the stick-slip phenomenon. Within the framework of Lyapunov theory, two control approaches based on different system representations are proposed.

Lyapunov-Based Stability Analysis
2014This chapter presents generalizations of the direct Lyapunov method to TDSs. In the first section, for general TDSs, the stability notions are defined, and Lyapunov–Krasovskii and Lyapunov–Razumikhin stability theorems are stated. The second section gives a short introduction to linear matrix inequalities. Sections 3.3–3.7 and 3.10 are devoted to delay-

Lyapunov-Based Stabilization of MEMS Relays
Journal of Dynamic Systems, Measurement, and Control, 2008In this paper, nonlinear stabilizers are introduced for voltage-controlled microelectromechanical system (MEMS) relays. The control constructions follow a Lyapunov approach and are based on a nonlinear dynamic model applicable to the two types of MEMS relays—electrostatic and electromagnetic.
