Control of Singular Systems with Random Abrupt Changes by El-Kébir Boukas

By El-Kébir Boukas

This booklet offers with the category of singular platforms with random abrupt adjustments sometimes called singular Markovian bounce structures. Many difficulties like stochastic balance, stochastic stabilization utilizing kingdom suggestions regulate and static output regulate, Hinfinity keep an eye on, filtering, assured rate regulate and combined H2/Hinfinity keep watch over and their robustness are tackled. regulate of singular structures with abrupt alterations examines either the theoretical and useful elements of the keep watch over difficulties handled within the quantity from the attitude of the structural houses of linear systems.

The concept offered within the various chapters of the amount are utilized to examples to teach the usefulness of the theoretical effects. keep an eye on of singular platforms with abrupt alterations is a wonderful textbook for graduate scholars in powerful regulate conception and as a reference for educational researchers up to speed or arithmetic with curiosity on top of things conception. The reader must have accomplished first-year graduate classes in likelihood, linear algebra, and linear structures. it's going to even be of significant worth to engineers working towards in fields the place the structures may be modeled by way of singular structures with random abrupt changes.

For any matrices U and V ∈ Rn×n with V > 0 , we have UV −1 U ≥ U + U − V . ) is trivial and can be found in the Appendix of [27]. ), note that since V > 0, we have the following: (U − V)V −1 (U − V) ≥ 0 , which yields UV −1 U − UV −1 V − VV −1 U + V ≥ 0 . This gives the desired results and ends the proof of the lemma. 6 Notes This chapter presented the class of Markovian jump singular systems also known as systems with random abrupt changes. Different concepts where presented and some models were developed to motivate the studies of this book.

Only the design problem for the continuous-time can be stated as LMI conditions. The discrete-time case remains an open problem. In some circumstances, the dynamical systems may have external disturbances that can not be modeled by Gaussian process to use the linear quadratic Gaussian technique to design the desired control. Under the assumption of finite energy or power of these external disturbances, the H∞ stabilization has been proposed to design controller to stabilize dynamical systems. For the last two decades, this stabilization problem has been tackled by some researchers among them we quote [40, 108, 68, 134, 89, 137, 128, 48, 124, 136, 93, 46, 106, 107] and the references therein.

The previous inequality matrix will hold if the following is satisfied: ⎡ ⎤ ⎢⎢⎢ J0 (i) Zi (X) Si (X) ⎥⎥⎥ ⎥ ⎢⎢⎢⎢ Z (X) −I 0 ⎥⎥⎥⎥ < 0 , ⎢⎣ i ⎦ Si (X) 0 −Xi (X) 53 54 3 State Feedback Stabilization with J0 (i) = X (i)A (i) + A(i)X(i) + Y (i)B (i) + B(i)Y(i) +λii X (i)E (i) . For the condition εP P(i) + P (i) ≥ E (i)P(i) = P (i)E(i) ≥ 0, we can transform it in a similar way to εP X(i) + X (i) ≥ X (i)E (i) = E(i)X(i) ≥ 0. If these conditions are satisfied for some set of nonsingular matrices X = (X(1), · · · , X(N)) > 0 and a set of matrices Y = (Y(1), · · · , Y(N)) for a fixed εP > 0, the closed-loop system will be piecewise regular, impulse-free and stochastically stable under the state feedback controller with a gain given by K(i) = Y(i)X −1 (i), i ∈ S .
