Abstract :
This paper considers fixed-structure stable H2-optimal controller synthesis using a multiobjective optimization technique. The problem is presented in a decentralized static output feedback framework developed for fixed-structure dynamic controller synthesis. A quasi-Newton/continuation algorithm is used to compute solutions to the necessary conditions. To demonstrate the approach, a numerical example is considered, which consists of a second-order spring-mass-damper system pulled from the stable stabilization literature. The results are then compared with other methods of stable compensator synthesis
