Abstract
In this study the walking type tractor-implement system is simplified to a three inertia system. The effect of equivalent inertia on the behavior of the tractor-implement system is clarified. The modeling of prototype closed-loop control of the tractor-implement system is derived and the identification of two kinds of parameters: closed-loop control parameters and physical system parameters are taken into account. This paper presents the theory and experiments used to perform this identification. It was found that the equivalent inertia was almost dominated by the engine inertia. The results obtained from the experiment and theory are in good agreement thus validating the effectiveness of the identification method.
