Research output: Contribution to journalArticlepeer-review


Concluding a series of three, this article deals with frequency domain methods when applied to systems subject to nonlinear dynamical effects. To meet increasing system requirements, techniques have to deal with the performance-degrading effects of nonlinearities. When applied with care, frequency domain methods provide practically applicable tools to model and optimise the performance of nonlinear systems. This article provides a brief overview and experimental examples of existing modelling techniques, as well as a novel method for performance assessment and optimisation using frequency domain based tooling.
