Gait Planning and Compensation Control of a Bipedal Humanoid Robot based on a Multi-link Model

The linear inverted pendulum (LIP) model with preview control is a standard approach for gait planning in bipedal humanoid robots. However, its inherent simplifications lead to significant model errors that compromise walking stability. To address this, we propose a compensation strategy that integrates two core components: a compensation controller based on a multi-link model and a joint torque trajectory generator based on full robot dynamics. Extensive simulations in ROS/MuJoCo demonstrate th
