Optimizing Static Linear Feedback: Gradient Method

A Gradient Method for the Static Output Feedback Mixed H2/H-Infinity Control

This paper is concerned with the mixed H2/H∞ control problem via static output feedback control. The main purpose of this paper is to give an iterative method for finding a sub-optimal static output-feedback controller for the mixed H2/H∞ control problem. The contribution of this paper is to derive a gradient of the H2 cost function. Using this gradient, we propose a gradient method for H2 and ...

I N T R O D U C T I O N In the last two decades, the s tudy of feedback stabilization for parabolic systems has gathered rauch attention from both mathematical and practical viewpoints. Let H be a Hilbert space equipped with the inner product {., "}H and the norm II • IIH. The control system with s ta te u is a d...

Pole Placement by Static Output Feedback for Generic Linear Systems

We consider linear systems withm inputs, p outputs and McMillan degree n, such that n = mp. If both m and p are even, we show that there is a non-empty open (in the usual topology) subset U of such systems, where the real pole placement map is not surjective. It follows that for each system in U , there exists an open set of pole configurations, symmetric with respect to the real line, which ca...

Optimizing KLIC with Static Analysis

Symbolic parallel languages, including KL1 and other parallel logic languages, are widely expected to solve various problems on parallel programming of non-numeric highly intelligent applications. With these languages, programmers will be comfortably free from complicated communication and synchronization among parallel objects, while PVM/MPI users struggle with these troublesome parallel stu s...
