This paper presents a new routing strategy based on the minimization of the worst-case queuing length. An H∞ optimal control scheme is proposed which can maintain a robust performance of the routing strategy in the presence of multiple and unknown time-varying network delays. First, the routing problem is formulated as an H∞ optimal control problem for a time delayed system. Towards this end, t...

This paper is concerned with the solution of state feedback H∞ control for a singleinput-single-output plant with parameters, and an algebraic approach that utilizes the so-called ‘sum of roots’ is developed. A method is firstly devised that computes a polynomial which contains the optimal cost as one of its roots. Furthermore it is shown that an optimal/suboptimal static feedback gain can be e...

this paper presents some analyses about the robust practical stability of a class of nonlinear affine systems in the presence of non-vanishing perturbations based on the passivity concept. the given analyses confirm the robust passivity property of the perturbed nonlinear systems in a certain region. moreover, robust control laws are designed to guarantee the practical stability of the perturbe...

the networked control system in modern control widely uses to decrease the implementation cost and increasing the performance. ncs in addition to its advantages is inevitable. nevertheless they suffer of some limitations and deficiencies. packet loss is one of the main limitations which affect the control system in different conditions and finally may lead to system instability. for this reason...

in this study, a robust controller is designed for fuzzy network control systems (ncss) using the static output feedback. delay and data packet dropout affect on the stability of network control systems, and therefore, the asymptotic stability condition is established considering delay and data packet dropout. delay is time-varying while the lower and upper bounds for delay is defined, and the ...
