This paper considers fixed-structure stable H-2-optimal controller synthesi
s using a multiobjective optimization technique which provides a trade-off
between closed-loop performance and the degree of controller stability. The
problem is presented in a decentralized static output feedback framework d
eveloped for fixed-structure dynamic controller synthesis. A quasi-Newton/c
ontinuation algorithm is used to compute solutions to the necessary conditi
ons. To demonstrate the approach, two numerical examples are considered. Th
e first example is a second-order spring-mass-damper system and the second
example is a fourth-order two-mass system, both of which are considered in
the stable stabilization literature. The results are then compared with oth
er methods of stable compensator synthesis. Copyright (C) 2000 John Wiley &
