Online iLQR-MPC with Whole-Body Control for Robust Humanoid Locomotion

Online iLQR-MPC with Whole-Body Control for Robust Humanoid Locomotion

Summary

This research paper introduces an online iterative linear-quadratic-regulator model predictive control (iLQR-MPC) framework integrated with whole-body control to achieve robust humanoid locomotion.

Editorial context

The authors present a model-based control framework combining iterative linear-quadratic-regulator MPC with whole-body control for humanoid locomotion, demonstrating disturbance recovery in simulation and on the Unitree G1 platform under specified impulsive push conditions.
