ZMP compensation for robocup3D based on the frequency signal

In this paper, we propose a new ZMP compensation method based on the frequency signal of the ZMP error in Robocup3D.The ZMP is defined as the point on the ground about which the sum of all the moments of the active forces equals zeros, and it’s an important point for the robot. The ZMP equation proposed in the following is used to represent the ZMP reference, and the sensor of the robot can gives us the ZMP response. Thanks to the ZMP compensation method proposed by Tomoya Sato and Kouhei, we proposed a new compensation method which can realize the dynamic stability during the robot’s walking process. The proposed method adjust feedback parameters according to the stability index and offer small torque to the robot in real-time which can ensure the dynamic stability of the robot .
