A Noise-filtering Event Generator for PIDPlus Controllers

In this paper we propose a new event generator, which has strong noise-filtering capabilities, to be used in event-based control systems with a {PIDPlus} controller. An approximate frequency analysis is performed in order to characterize the event generator system and tuning guidelines are provided for its design parameter. Simulation and experimental results obtained with a laboratory setup demonstrate the effectiveness of the methodology in providing a satisfactory performance related to set-point and load disturbance step responses with a total variation that is significantly reduced with respect to the standard cases.
