this paper presents h∞ control problem for input-delayed systems. a neutral system approach is considered to the design of pd controller for input delay systems in presence of uncertain time-invariant delay. using this approach, the resulting closed-loop system turns into a specific time-delay system of neutral type. the significant specification of this neutral system is that its delayed coeff...

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 ...

Closed-loop controllers use outputs of the system to improve overall stability and increase tolerance against external disturbances. The latter makes it possible to control inherently unstable systems. As expected, there are some important differences from open-loop controllers. Most importantly, we must distinguish between measurable outputs of the system and the properties we really want to c...

in this paper, we try to use modeling based on singular perturbation theory, in order to control satellite attitude during the wide rolling angle maneuvering through nonlinear h∞ control strategy. differential equations describing dynamics of the satellite are presented first, and by choosing the appropriate dynamic model for actuators and based on the standard singular perturbation model, the ...

This paper introduces a new method for the synthesis of gate-level asynchronous controllers. The method is based on a user-level specification formalism, the path model, and a simple algebraic tool, the signal calculus, that in combination provide a formalism for the specification and analysis of path-model designs. The path model view of communication is state-based as in other asynchronous fi...
