Abstract
The philosophical issues pertaining to the problem of going from experiment to controller design are discussed. The “unfalsified control” concept is introduced as a framework for determining control laws whose ability to meet given performance specifications is at least not invalidated (i.e., not falsified) by the available data. The approach is “model-free” in the sense that no plant model is required — only plant input-output data. When implemented in real time, the result is an adaptive robust controller which modifies itself whenever a new piece of data invalidates the present controller. A simple design example based on fixed-order LTI controllers and an L 2-inequality performance criterion is presented.
The task of science is to stake out the limits of the knowable and to center the consciousness within them.
