摘要：AbstractIn this paper, we propose a derivative-dependent controller to regulate the dynamic response of a fuel cell system. Since derivatives are in general difficult to measure or construct reliably, it is a common practice to approximate them using finite-differences. This approximation, if not performed carefully, may produce undesired control activity or even instability. Here, we propose to engineer the finite-differences using artificial delays to avoid undesired outcomes thus guaranteeing a stable implementation of the control scheme. Effectiveness of the approach is carried out via time-simulations.
