摘要:In this paper we propose a model with four degrees of freedom for hand-arm-forearm dynamic system. Using experimental data from [9]by means of the Simulink program, is built block diagram to simulate the dynamic system motion and phase diagrams are drawn by using Matlab. From the interpretation of these diagrams result, for a set of parameters ( m, c, k, FO, ω ), stable moves for the hand-arm-forearm dynamic system.
