In this paper the solutions to the optimal multiobjective H 2 / H D 0 problem are characterized using Banach space duality theory, and shown to satisfy a flatness or allpass condition. Dual and predual spaces are identified, and equivalent maximizations formulated therein. The duality description leads naturally to a solution based on convex programming.

A worst-case mixed H 2 =H 1-optimal control problem is formulated and solved for sampled-data systems. The solution is obtained in terms of a set of synthesis equations, which correspond to similar synthesis equations for the continuous and discrete mixed H 2 =H 1 problems. The mixed H 2 =H 1 problem can be applied to the design of controllers which achieve robust H 2 performance for uncertain ...

2 on the H performance level, while satisfying the H performance. The proposed hybrid control scheme is based on a fuzzy supervisor which manages the combination of two controllers. A convex LMI-Based formulation of the two fast and slow subsystem controllers leads to a structure which ensures a good performance in both the transient phase and the steady state phase. The stability analysis uses...

Simultaneous routing and resource allocation has been considered in wireless networks for its performance improvement. In this paper we propose a cross-layer optimization framework for worst-case queue length minimization in some type of FDMA based wireless networks, in which the the data routing and the power allocation problem are jointly optimized with Fuzzy distributed H∞ control strategy ....

Todays, use of combination of two or more methods was considered to control of systems. In this paper ispresented how to design of a nonlinear H∞ (NL-H∞) controller for flexible joint robot (FJR) based on boundedUKF state estimator. The UKF has more advantages to standard EKF such as low bios and no need toderivations. In this research, based on spong primary model for FJRs, same as rigid robot...

The genus Hypericum is one of the most important medicinal plants that contain 17 species in Iran, three of them are endemics. This paper reports the essential oil composition of eight Hypericum species from Iran. The essential oil analysis of a number of the studied plants has already been reported but their report from Iran may be valuable for scientists.  Samples collected from different pla...

In this paper‎, ‎the concept of synchronization control along with robust H∞ control are considered to evaluate the seismic response control on multi-story structures‎. ‎To show the accuracy of the novel algorithm‎, ‎a five-story structure is evaluated under the EL-Centro earthquake load‎. ‎In order to find the performance of the novel algorithm‎, ‎random and uncertainty processes corresponding...
