Abstract

The invention discloses a virtual passive walking robot speed adjusting method and device, a storage medium and a terminal. The method comprises the steps: a speed adjusting process is executed according to a preset mode, wherein the speed adjusting process comprises the steps of acquiring an executing target speed and calculating an executing target gravitational acceleration and executing targetwalking kinetic energy; the actual speed of the virtual passive walking robot is obtained and the actual walking kinetic energy is calculated; a kinetic energy error is calculated according to the executing target walking kinetic energy and the actual walking kinetic energy; the kinetic energy error and the executing target gravitational acceleration are transmitted to a closed-loop virtual passive walking speed controller, and a control signal output by the closed-loop virtual passive walking speed controller is received. According to the method, parameters of controllers such as the executing target speed gravitational acceleration and the target walking kinetic energy are calculated according to the executing target speed, feedback control is carried out according to the error betweenthe actual kinetic energy and the target walking kinetic energy and the executing target gravitational acceleration, finally, speed switching is achieved, and the whole system is ensued to tend to bein a stable state.

Description

technical field [0001] The invention relates to the technical field of virtual passive walking speed adjustment of a compass-like biped walking robot, in particular to a speed adjustment method and device, a storage medium and a terminal of a virtual passive walking robot. Background technique [0002] At present, the dynamic performance, energy efficiency ratio and stability of biped walking robot walking gait are very important indicators. In addition to the active full gait control walking method based on the ZMP rule, the current biped walking robot is becoming more and more important based on the virtual passive walking gait control method based on the simulated passive walking gait. [0003] Passive walking means that the biped walking robot relies entirely on its own gravity to achieve stable walking on a slope with a certain downward inclination angle without the help of external driving torque. This walking method is a natural and low-energy walking gait, which is ...
