Experimental Identification of Electronic Throttle Body

Proceedings of 10th European Conference on Power Electronics and Applications (EPE 2003), Toulouse, France, 2003
Detailed off-line experimental identification of an automotive electronic throttle body (ETB) is carried out with the aim to aid design of a high-performance electronic throttle control strategy. The linear and nonlinear parts of the ETB model are conveniently identified separately. Identification of ETB linear dynamics includes a multi-step identification method based on physical ETB model form, and single-step methods based on the black-box continuous-time and discrete-time ETB model forms. The nonlinear effects identified include static and dynamic friction effects and distinctive limp-home nonlinearity.
