Journal ArticleDOI
On plant and LQG controller continuity questions
TL;DR: It is shown that it is possible to calculate a new optimal LQG controller from a previous one when the plant is slightly changed, and to quantify the change in the controller as a function of thechange in the plant.
Journal ArticleDOI
Stability properties of linear systems in phase-variable form
TL;DR: In this paper, a connection between Lyapunov stability and bounded-input, bounded-output stability is established for systems which may be represented in a special canonical form; the extent to which systems can be put into this canonical form has been discussed by others and is reviewed at the end of the paper.
Journal ArticleDOI
Quantitative effects of weight adjustments in ℋ︁∞ control
TL;DR: In this article, the authors seek to understand and provide quantitative results on how weight adjustments directly affect an ℋ∞ controller and, more importantly, the corresponding closed-loop transfer function matrices.
Proceedings ArticleDOI
Nonlinear analysis for verifying closed-loop stability before inserting a new controller
TL;DR: This paper extends the results for linear time-invariant systems and proposes novel nonlinear analysis results, utilizing the kernel representation of nonlinear systems, for ensuring that the introduction of the new nonlinear controller will stabilize the plant.
Proceedings ArticleDOI
Frequency domain image of a set of linearly parametrized transfer functionst
TL;DR: It is shown that the probability level for the frequency domain set is generally larger than the probability for the parametric set, due to the fact that the mapping between parametric and frequency domain spaces is not bijective.
