In this thesis project a robust control for an electronic throttle valve(ETV) is developed. The thesis is held in collaboration with the company Testing Technologies s.r.l. The designed controller is intended to be used for testing purposes by exploiting the testbench of the company, in particular the aim is to have a controller able to adapt to different valve models and so to be independent from the parameters of the valve itself in order to speed up the testing procedure and to avoid the re-characterization of the model for every valve. After an introduction and overview on the state-of- the-art, the mathematical model of the valve is presented.
