Abstract

The invention discloses a biped robot stable walking control method, device, equipment and readable medium, comprising: constructing a simplified rigid body dynamics model of a biped robot; based on a model predictive control method, using the simplified rigid body of the biped robot A dynamic model is used to construct a center-of-mass state prediction model; according to the center-of-mass state prediction model, the optimization equation group in the model predictive control method is simplified into a quadratic programming equation group; the quadratic programming equation group is solved to obtain an optimized ground reaction force, thereby obtaining A control parameter for stable walking; controlling the biped robot according to the stable walking control parameter. The present invention analyzes the problem through the center of mass control framework, simplifies the analysis of the control of each part of the body during the walking process of the robot, and at the same time, the method of model predictive control is predictive compared with the traditional feedback control method, so that the robot has the ability to walk on unknown rough roads. Better robustness.

Description

technical field [0001] The invention relates to a robot control method, in particular to a biped robot stable walking control method, device, equipment and readable medium. Background technique [0002] As a tool used by humans to improve production efficiency and improve life, robots have always received a lot of attention. Compared with industrial robots and wheeled robots, biped robots can better adapt to complex road surfaces and cross obstacles to a certain extent through discrete footholds because of their human-like structure. flexibility. At the same time, biped robots have the same flexibility as humans, and can easily adapt to the environment of human life and use tools made by humans. It is foreseeable that in the future, humans will use a large number of biped robots to replace humans to complete dangerous or repetitive tasks. [0003] Stable walking of biped robots has always been one of the hotspots in the research field of biped robots. As the basis of a s...
