Multiparameter Fractional Difference Linear Control Systems
Discrete Dynamics in Nature and Society, 2014 The Riemann-Liouville-, Caputo-, and Grünwald-Letnikov-type fractional order difference operators are discussed and used to state and solve the controllability and observability problems of linear fractional order discrete-time control systems with ...

Optimal Finite-time Control of Positive Linear Discrete-time Systems [PDF]
Journal of Electrical and Computer Engineering Innovations, 2016 This paper considers solving optimization problem for linear discrete time systems such that closed-loop discrete-time system is positive (i.e., all of its state variables have non-negative values) and also finite-time stable.

Finite-Time Control of Singular Linear Semi-Markov Jump Systems
Algorithms, 2021 The problem of finite-time control for singular linear semi-Markov jump systems (SMJSs) with unknown transition rates is considered in this paper. By designing a new semi-positive definite Lyapunov-like function, state feedback controller design methods ...

Controllability of Continuous Bimodal Linear Systems [PDF]
Mathematical Problems in Engineering, 2013 We consider bimodal linear systems consisting of two linear dynamics acting on each side of a given hyperplane, assuming continuity along the separating hyperplane. We prove that the study of controllability can be reduced to the unobservable case, and for these ones we obtain a simple explicit characterization of controllability for dimensions 2 and 3,

Event-Triggered Consensus Control for Linear Multi-Agent Systems
IEEE Access, 2019 For the consensus problem of multi-agent systems with linear dynamics, distributed event-triggered control strategies are put forward, which can decrease the frequency of information transmissions between agents and the number of control inputs of each ...

The Use of Linear Control Laws with Non-Linear Systems
Measurement + Control, 1976 The problem of providing optimal regulation of non-linear systems has been one of long standing and has been solved usually by empirical techniques with, seemingly, no relief provided by the methods based on the newer theories of control.

Linear quadratic power control for CDMA systems
Journal of Telecommunications and Information Technology, 2003 In this paper, we present a robust decentralized method for jointly performing channel estimation and closed loop power control for the reverse link of CDMA networks. Our method, based on linear quadratic Gaussian (LQG) control systems theory and Kalman

Non-linear control model for use in greenhouse climate control systems
Research in Agricultural Engineering, 2022 In this study, a non-linear control system was designed and proposed to control the greenhouse climate conditions. This control system directly uses the information of sensors, installed inside and outside the greenhouse.

Polynomial controllers for linear systems
Mathematical and Computer Modelling, 2001 In this paper, we study the problem of controlling a linear system with polynomial controls. We establish upper bounds of admissible polynomial controls in two special cases: systems with distinct eigenvalues and systems with all real eigenvalues. For certain other classes we show that the existence of such control of a minimum possible degree is ...
