Optimal fluctuations for satisfactory performance under parameter uncertainty

Maintaining constant performance in the presence of a set of changes in parameters and unwarranted events has become an essential aspect of present system designs. Knowing a predefined upper limit, for which a drop in performance is said to be satisfactory, enables autonomous systems to perform a control action to mitigate changes that violate such a predefined limit. This paper introduces an analytical model for optimisation of the maximum possible parameter fluctuations that permit robust operation.
