| Abstract(in English) | A three-link and three-joint optimal control model to reproduce human squat movements has already been proposed. This model is characterized by successively optimizing the half-crouching process and the rising-up process of squat movements. However, this model has a difficulty in deriving the desired value of the state variable for optimizing the model's half-crouching process. This research proposes a more advanced optimal control model through developing a mechanism to predict the value of the state variable at the switching time. Consequently, the following results are obtained: (1) the proposed model can predict the value of the state variable at the switching time as a linear function of the minimum height of the center of gravity at the same time; (2) the proposed model can successfully reproduce measured squat movements by using the predicted value of the state variable; (3) there exists the optimum switching time to minimize the model's overall criterion function. These results suggest that the proposed model can be an effective and plausible model of the human squatting mechanism and that the switching time and the state variable of that time can be factors involved strongly in human squat movements. |
