Data-driven multivariable controller design using Ellipsoidal Unfalsified Control

Data-driven Robust Control Design: Unfalsified Control

Feedback control systems for aerospace applications must maintain precise control despite uncertain operating conditions and unanticipated circumstances such as battle damage. These systems must be designed to perform robustly, despite uncertain design models and difficult to analyze nonlinear effects. They must also be capable of learning and adapting when accumulating data indicates that prev...

Unfalsified Control Using an Ellipsoidal Unfalsified Region Applied to a Motion System

In this paper, unfalsified control theory (a data-driven model-free control theory) is applied to determine which control parameter sets in a specified control structure are able to meet a given performance specification, using merely measured input/output data. The need for a finite, often large, amount of parameter sets (“gridding”) is overcome by applying an ellipsoidal description of the re...

Asymptotically exact direct data-driven multivariable controller tuning

In this paper, a data-driven controller design method for multivariable systems is introduced and analyzed. The proposed technique is direct, as it is entirely based on experimental data and does not rely on a physical description of the system, and non-iterative, as it does not require controller adjustments based on additional experiments. Compared to the state-of-theart non-iterative techniq...

Multi-model unfalsified switching control of uncertain multivariable systems

Direct data-driven recursive controller unfalsification with analytic update

Unfalsified Control is a data-driven, plant-model-free controller design method, which recursively falsifies controllers that fail to meet the specified performance requirement. In Ellipsoidal Unfalsified Control, the region of controllers that are unfalsified, the Unfalsified set, is described by an ellipsoid. Due to the combination of the performance requirement and controller structure, the ...
