We consider minimal controllability problems (MCPs) on linear structural descriptor systems. address two of determining the minimum number input nodes such that a system is structurally controllable. show MCP0 for systems can be solved in polynomial time. This same as existing results typical time invariant (LTI) However, derivation result considerably different because technique cannot used In...

In this paper, we study the classical problem of stabilizing a Linear Time Invariant (LTI) system in a packet-based network setting. We assume that the LTI system is unstable but both controllable and observable. The state information is transmitted to the controller over a packetbased network. We also assume that there is a perfect link from the controller to the plant. We give a set of suffic...

State estimation of linear time-invariant (LTI) systems by using a network distributed observers is studied in this paper. We assume that each observer has access to local measurement which may be insufficient provide the observability system, but ensemble all measurements guarantees observability. In condition, objective design state approach such that, while can exchange their estimated vecto...

In this paper, a new control scheme, called additive-state-decomposition-based tracking control, is proposed to solve the tracking (rejection) problem for rotational position of the TORA (a nonlinear nonminimum phase system). By the additive state decomposition, the tracking (rejection) task for the considered nonlinear system is decomposed into two independent subtasks: a tracking (rejection) ...

Presently, linear parameter varying (LPV) systems are broadly used in a wide range of applications such as in aerospace, energy, health, mechatronics, process control, computational systems, etc. Essentially, an LPV system is a linear system whose parameters are functions of a scheduling signal. It can be described by state-space or input/output models, in continuous or discrete-time. The incre...

Spectral analysis and system identification techniques require suitably long data sets. Linear time-invariant (LTI) systems under random input can be demanding in terms of accurate simulation all dynamics because calculation time. This paper details an extension the state-space formulation LTI for higher order holds, periodic exponential inputs. Exact solutions differential state equation are i...

Abstract: This paper presents a scheme for designing a robust decentralized PI controller for an industrial utility boiler system. First, a new method for designing robust decentralized PI controllers for uncertain LTI MIMO systems is presented. Sufficient conditions for closedloop stability and diagonal dominance of a multivariable system are given. For each isolated subsystem a first order ap...

This paper studies the global asymptotic stability of a class of fuzzy systems. It demonstrates the equivalence of stability properties of fuzzy systems and linear time invariant (LTI) switching systems. A necessary condition and a sufficient condition for the stability of such systems are given, and it is shown that under the sufficient condition, a common Lyapunov function exists for the LTI ...

In the previous papers (Pupeikis, 2000; Genov et al., 2006), a direct approach for estimating the parameters of a discrete-time linear time-invariant (LTI) dynamic system, acting in a closed-loop in the case of additive correlated noise with contaminating outliers uniformly spread in it, is presented. It is assumed here that the parameters of the LQG (Linear Quadratic Gaussian Control) controll...
