✦ Synopsis

This paper considers "xed-structure stable H -optimal controller synthesis using a multiobjective optimization technique which provides a trade-o! between closed-loop performance and the degree of controller stability. The problem is presented in a decentralized static output feedback framework developed for "xed-structure dynamic controller synthesis. A quasi-Newton/continuation algorithm is used to compute solutions to the necessary conditions. To demonstrate the approach, two numerical examples are considered. The "rst example is a second-order spring}mass}damper system and the second example is a fourthorder two-mass system, both of which are considered in the stable stabilization literature. The results are then compared with other methods of stable compensator synthesis.

In this paper a numerical solution is obtained to the problem of minimizing an H -type cost subject to an H -norm constraint. The method employed is based on the convex alternating projection algorithm and generalizes a recent technique to the multivariable case. The solution is derived in terms of

In this paper, we consider the problem of finding controllers which place the eigenvalues of the closed-loop system matrix in a prespecified circular region in the left-half plane and minimize an associated quadratic cost function. We give solutions to both state-feedback and outputfeedback synthesi

H , / H , optimal control synthesis enables the design of controllers for simultaneous rejection of both narrow-band and wide-band disturbances and also has applications in robust control. Synthesis equations in the form of coupled Riccati and Lyapunov equations are available for both full-order and
