Simulations of Robust Control of the Throttle Valve Position

The paper presents design, modeling and simulation of robust control applied to the throttle valve position. For this purpose, the simplified mathematical model of the throttle valve is first presented. It consists of a second order system affected by parameters uncertainties. Because of these drawbacks, H2 and H-infinity methods are used to design the controllers that assure good performances and robustness properties. The design and simulation results are obtained using Robust Control Toolbox from the Matlab environment.
