Information from the describing function of the non linearity that introduces the event-based sampling strategy and measures of the oscillations are used to generate the estimations. The event-based sampling condition applied is based on the sampling strategy known as symmetric-send-on-delta.engAtribución-NoComercial-CompartirIgual 4.0 Españahttp://creativecommons.org/licenses/by-nc-sa/4.0/es/Describing functionEvent-based controlSend-on-deltaEstimationLimit cycleconference outputopen accesshttps://doi.org/10.17979/spudc.9788497497749.0174
