Robust Data-Driven Output Feedback for Systems With Unknown Input Delays
Ngoc Tuan Dinh, Ba Huy Nguyen, Alexey Peregudin +1
In a history-feedback realization, an input delay increases memory without increasing the number of unknown physical coefficients. We use this structure to design output-feedback c…
Sharp approximation thresholds for power means of common-subspace volumes
Alexey Peregudin
We study how well a single -dimensional subspace can preserve volume from several positive semidefinite matrices at once. Each matrix is compressed to the subspace and scored by…
Minimal Experiments for Robust Stabilization: Information, Spectral Geometry, and Duration
Alexey Peregudin, Ngoc Tuan Dinh
On broad classes of linear systems, the shortest experiments are almost as good as the best possible ones. For states and inputs, the shortest input sequences that support…
Globally Certified Invariant-Ellipsoid Control from Data
Ngoc Tuan Dinh, Egor Dogadin, Alexey Peregudin
This letter develops a data-based method for designing state feedback for a discrete-time linear system under bounded disturbances. For each admissible feedback gain and scalar des…
Sharp Quadratic Majorants of Weighted Power Means of Quadratic Forms
Alexey Peregudin
We study when concave weighted power means of positive semidefinite quadratic forms admit sharp quadratic upper bounds. The starting point is the scalar fact that each such mean is…
Exact Noise Limits for Bounded Scalar Stabilization Experiments
Alexey Peregudin, Ngoc Tuan Dinh
How much unknown process noise can a bounded experiment tolerate while still establishing that the plant can be stabilized? We answer this question for scalar discrete-time systems…
