We consider the problem of robust feedback control of LTI systems in the presence of parasitics. An essential related concept is that of fast stability -- a type of stability characterizing parasitics or high-frequency effects. A rigorous definition of fast stability is formulated in terms of topologies on a certain differentiable manifold and is connected with the robust feedback problem. A generic solution is given along with illustrative examples.

A new approach to multi-rate sensor measurement feedback is described based on the stochastic, digital output feedback regulator problem. The objective is to find the constant gain feedback control system which feeds back sensor measurements at different rates and minimizes a discrete quadratic cost function. An iterative algorithm which can be used to compute the optimal multi-rate output feedback gain is presented.

This paper, considers the behavior of the finite optimal closed-loop poles for non-square multivariable systems. It is shown that, if the system is nonsquare, then some of the optimal closed loop poles asymptotically approach the location of (minimum phase) transmission zeros (or reflections of the non-minimum phase ones), some approach infinity, and yet others approach new locations, unrelated to the transmission zeros. These locations are referred to as "compromise zeros" A numerically stable technique is used to solve for the compromise zeros. The paper also investigates the behavior of optimal regulators in which the weighting matrices are chosen via the implicit model-following technique.

A prototype expert system for the treatment of stochastic control and nonlinear filtering problems is described with several illustrative examples. The system is written in MACSYMA and Lisp. It accepts user input in natural language or symbolic form; it carries out the basic analysis of the user's problem in symbolic form; and it produces FORTRAN code for the numerical reduction of the problem. The system has a module using PROLOG to check the well-posedness of linear and nonlinear partial differential equations specified in symbolic form. Sample sessions with the system are presented to illustrate its operation.
