In this paper, the method of modern control approach for the design of controller and observer is used. Other functions such as neural controllers - or fuzzy sliding mode control can be found in this work and the results are compared. First, a dynamic model of the servo valve is intended for the governing equations in state-space form expression are obtained. Due to the system integrator is exp...

We describe a class of rank-2 graphs whose C∗-algebras are AT algebras. For a subclass which we call rank-2 Bratteli diagrams, we compute the K-theory of the C∗-algebra. We identify rank-2 Bratteli diagrams whose C∗-algebras are simple and have real-rank zero, and characterise the K-invariants achieved by such algebras. We give examples of rank-2 Bratteli diagrams whose C∗-algebras contain as f...

this paper describes an optimal design for multivariable pi controller with a high gain structure for an irregular system by genetic algorithm. pi controllers with a high gain structure leads to the asymptotic decomposition of the fast and slow modes in the closed loop system that have unique characteristics. the slow modes are asymptotically uncontrollable and unobservable; therefore, they hav...

In this article we study the expected rank problem under full information. Our approach uses the planar Poisson approach from Gnedin (2007) to derive the expected rank of a stopping rule that is one of the simplest non-trivial examples combining rank dependent rules with threshold rules. This rule attains an expected rank lower than the best upper bounds obtained in the literature so far, in pa...

Lattice Definition. (Lattice) Given n linearly independent vectors b1, , bn ∈ R, the lattice generated by them · · · is defined as L(b1, b2, · · · bn) = { xibi|xi ∈ Z}. We refer to b1, · · · , bn as a basis of the lattice. Equivalently, if we define B as the m × n matrix whose columns are b1, , bn, then the lattice generated by B is · · · L(B) = L(b1, b2, · · · , bn) = {Bx|x ∈ Z}. We say that t...

The structure of Steiner quadruple system S(v, 4, 3) of full 2-rank v− 1 is considered. It is shown that there are two types (induced and singular) of such systems. It is shown that induced Steiner systems can be obtained from Steiner systems S(v, 4, 3) of 2-rank v − 2 by switching construction which is introduced here. Moreover, all non-isomorphic induced Steiner systems S(16, 4, 3) of full 2r...

We establish structural controllability results for matrix pairs [A, B] where .4=A0+Z piAi, B=B,+Z piB', with tho At, Bi fixed, and the pr free scalar parameters. Tho results characterize structural controllability in several wsys, via, tests involving the cllecking of the rank or the evaluation of the determinant of various constant matrices formed from t,he At, Bi. A number of the result,^ us...
