One strength of the LIP model is that it is simple enough to lend itself to thorough mathematical analysis. Notably, the divergent part of its dynamics can be represented by a single component, the divergent component of motion (DCM), rather than the full CoM state (position and velocity). Linear feedback …

WebOct 29, 2024 · Abstract¶. Some nonlinear control systems admit an exponential dichotomy (Coppel, 1966), that is to say, their dynamics can be decomposed into (exponentially) stable and unstable components. Walking robots fall into this category, and we call their unstable components divergent components of motion (DCM). The concept of DCM has been … WebIn the paper, an improved model predictive control (MPC) method based on the divergent components of motion (DCM) is proposed. Firstly, the humanoid robot model is …
WebMar 28, 2024 · To analyze gait motions using these limited sensors, the divergent component of motion (DCM) of the user is computed. The DCM is a physical quantity incorporating the linear position and linear velocity of the center of mass; these can be computed from the kinematic data of a support leg. In each of the three gait states SA, …
