【 摘 要 】

In this paper, a data-driven method is proposed to estimate lower bounds of the gain and phase margins without the mathematical model of a plant. To estimate the stability margins, which are defined in the frequency domain, using input/output data, we describe lower bounds in the time domain. Then, we formulate an optimization problem to estimate a lower bound of each stability margin and propose an iterative data-driven algorithm to solve this problem. (c) 2023 The Authors.
