This paper introduces an analytical formulation to describe QFT templates based on Fourier series. This allows to calculate the template contour of plants with a high number of uncertain parameters. The proposed solution consists of performing operations between analytical sub-templates. This saves calculation time and allows to work with an infinite set of plant values.
This paper deals with the discrete time control of an omnidirectional mobile robot subject to transport delays. A discrete-time model of the vehicle is obtained by considering an exact discretization of the continuous time model of the robot where the time delay induced by a communication network is considered. The path-tracking problem is addressed by means of a prediction strategy based on the well...
This paper deals with static output feedback Hinfin control of a class of discrete-time networked control systems (NCSs) subject to random failures and random delays. The different random processes are modeled as Markovian chains, and the resulting closed-loop system belongs to the class of discrete-time Markovian jump linear systems (MJLS). For synthesis purposes, we adopt a new framework, based...
The paper is focused on control of first order unstable delayed systems. The control design is performed in the RMS ring of retarded quasipolynomial (RQ) meromorphic functions. Unstable systems are modeled in anisochronic philosophy as a ratio of quasipolynomials where also denominator contains delay terms. The goal is to find a suitable stable quasipolynomial as a common denominator of RMS terms...
The problem of control law design for a system consisting of linear stationary and static nonlinear parts is considered. It is supposed that parameters of the linear block are unknown, and its input-to-output transfer function is minimum phase. It is assumed that nonlinear part of the system is known inaccurately, irreducible to the linear block input and, generally, does not satisfy sector restrictions...
