In this paper, we propose a control algorithm for quadruped walking robots to track the Zero Moment Point (ZMP) trajectory using Preview Control. In critical moment of trot pace, we can assume the robot as a linear inverted pendulum so that the linear inverted pendulum model can be applied to describe the dynamic behavior of our quadruped robot. A preview controller therefore is designed for this...
Based on the analysis of relative orbit dynamics for GEO (geostationary orbit, GEO) satellite and LQG (Linear Quadratic Gaussian, LQG) algorithm, this paper proposed a station-keeping control method for GEO satellite, which realized north-south station-keeping and west-east station-keeping simultaneously. To further verify the effectiveness of the proposed method, corresponding mathematical simulation...
