Supervisory control of a class of discrete event processes
Peter J. Ramadge,W. M. Wonham +1 more
TL;DR: In this paper, the control of a class of discrete event processes, i.e., processes that are discrete, asynchronous and possibly non-deterministic, is studied. And the existence problem for a supervisor is reduced to finding the largest controllable language contained in a given legal language, where the control process is described as the generator of a formal language, while the supervisor is constructed from the grammar of a specified target language that incorporates the desired closed-loop system behavior.

The control of discrete event systems
Peter J. Ramadge,W. M. Wonham +1 more
TL;DR: The focus is on the qualitative aspects of control, but computation and the related issue of computational complexity are also considered.

Paper: The internal model principle of control theory
B. A. Francis,W. M. Wonham +1 more
TL;DR: The Internal Model Principle is extended to weakly nonlinear systems subjected to step disturbances and reference signals and is shown that, in the frequency domain, the purpose of the internal model is to supply closed loop transmission zeros which cancel the unstable poles of the disturbance andreference signals.
Journal ArticleDOI
The internal model principle for linear multivariable regulators
Bruce A. Francis,W. M. Wonham +1 more
TL;DR: In this paper, structural stability of linear multivariable regulators is defined and necessary and sufficient structural criteria are obtained for linear multi-variable regulators which retain loop stability and output regulation in the presence of small perturbations, of specified types, in system parameters.
