Item Open Access Algebraic theory of linear multivariable control systems(Bilkent University, 1998) Çetin, Sevgi BabacanThe theory of linear multivariable systems stands out as tlie most developed and sophisticated among the topics of system theory. In the literature, many different solutions are presented to the linear midtivariable control problems using three main approaches : geometric approacli, fractional approach and polynomial model based approach. This thesis is a first draft for a textbook on linear multivariable control which contains a description of solutions to the most of the standard algebraic feedback control problems using simple linear algebra and a minimal amount of polynomial algebra. These problems are internal stabilization, disturbance decoupling by state feedback and measurement feedback, output stabilization, tracking with regulation in a scalar system, regulator problem with a single output channel and decentralized stabilization.Item Open Access Decentralized control and periodic feedback(IEEE, 1994) Khargonekar P. P.; Özgüler, A. B.The decentralized stabilization problem for linear, discretetime, periodically time-varying plants using periodic controllers is considered. The main tool used is the technique of lifting a periodic system to a time-invariant one via extensions of the input and output spaces. It is shown that a periodically time-varying system of fundamental period N can be stabilized by a decentralized periodic controller if and only if: 1) the system is stabilizable and detectable, and 2) the N-lifting of each complementary subsystem of identically zero input-output map is free of unstable input-output decoupling zeros. In the special case of N = 1, this yields and clarifies all the major existing results on decentralized stabilization of time-invariant plants by periodically time-varying controllers. © 1994 IEEEItem Open Access Decentralized stabilization of interconnected systems: Structural conditions(1992) Yu, R.; Sezer, M. E.A unified framework is provided for the design of high-gain decentralized controllers for the stabilization of several classes of interconnected systems. These classes are characterized in terms of the structure of the interconnections among the subsystems, and include all those known in the literature to be decentrally stabilizable. The simple decentralized stabilizability tests, on which the results are based, can also be used to check the stabilizability of individual interconnected systems that do not belong to any one of the classes considered.
