A New Geometric Stability Margin for Feedback Systema.
(1987)
This paper provides a new geometric concept for a stability margin for feedback control systems which is applicable for any number of inputs and outputs. The measure of stability margin employed has the advantage over ...
The Conditional Adjoint Process.
(1988)
The adjoint and minimum principle for a partially observed diffusion can be obtained by differentiating the statement that a control u* is optimal. Using stochastic flows the variation in the cost resulting from a change ...
On Observer Problems for Systems Governed by Partial Differential Equations.
(1986)
The problem of observers has been introduced in control literature. Let us consider a dynamic system which is deterministic, but whose initial state is unknown. An observer is a model which mimics the behavior of the ...
An Impulse Control Problem for a Stochastic PDE Arising in Non Linear Filtering.
(1987)
We consider the nonlinear filtering problem of a vector diffusion process, when several noisy vector observations with possibly different dimension of their range space are available. At each time any number of these ...
Dynamic Observers as Asymptotic Limits of Recursive Filters: Special Cases.
(1986)
A method for constructing observers for dynamical systems ae asymptotic limits of filters is described. The program is carried out in detail for linear systems, and in addition, an observer is obtained for a class of systems ...
Controlled Computations or Computer Control
(1986)
In this position paper some critical issues between control engineering technology and computer technology (both hardware and software) are examined. In the process we identify some promising opportunities for future ...
Systems Research Center.
(1987)
The Systems Research Center (SRC) at the University of Maryland, College Park, and Harvard University, Cambridge, Mass., is a new forum for fundamental research and education in systems engineering. Established by a National ...
