The purpose of this paper is to propose a high-frequency MPC control method for the bounding gait of a parallel quadruped robot.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title content-type=\"abstract-subheading\">Design\/methodology\/approach<\/jats:title>\n<jats:p>According to the bounding gait characteristics of the robot, the quadruped robot model is simplified to an equivalent plane bipedal model. Under the biped robot model, the forces between the robot\u2019s feet and the ground are calculated by MPC. Then, the authors apply a proportional differential controller to distribute these forces to the four feet of the quadruped robot.

Experiments show that the update frequency of MPC could be stabilized at 500 Hz while the robot was running in the bounding gait stably and
