Abstract
Electromechanical Valve Actuators (EMVA) are fundamental components of camless engines. This work is concerned with the experimental validation of the bifurcation behaviour of an EMVA controlled via a so-called "key-on" feedback controller. The experimental results are validated via an appropriate mathematical model and the existence of limit cycles proved analytically by using a describing function approach. The numerical and theoretical analysis are shown to capture the observed experimental behaviour.File in questo prodotto:
