- When a derivative-dependent control is implemented in hardware, the derivatives are approximated using delayed measurements. This paper, supported by Israel Science Foundation (grant 1128/14), provides a method of verifying that such an approximation preserves the system performance and provides guidance on controller parameter selection. The results were subsequently used to obtain a robust version of the classical proportional-integral-derivative (PID) controller where the derivative is replaced by the delayed output (doi.org/10.1109/CDC.2018.8619030). The work was cited in a successful application for an Israel Science Foundation grant (ISF 673/19).
