Abstract

The invention discloses a stable walking control method and device for a biped robot, equipment and a readable medium. The stable walking control method comprises the steps: constructing a simplifiedrigid body dynamic model of a biped robot; constructing a centroid state prediction model by using the simplified rigid body dynamic model of the biped robot based on a model prediction control method; simplifying an optimization equation set in the model prediction control method into a quadratic programming equation set according to the centroid state prediction model; solving the quadratic programming equation set to obtain optimized ground reaction force so as to obtain stable walking control parameters; and controlling the biped robot according to the stable walking control parameters. According to the method, a problem is analyzed through the centroid control framework, and analysis of control over all parts of the body in the walking process of the robot is simplified; meanwhile, compared with a traditional feedback control method, the model prediction control method has high predictability, so that the robot has better robustness when walking on an unknown rugged road surface.

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...
