UnverifiedWhole-body control (WBC) treats the robot as a unified dynamic system, simultaneously computing torque commands for all joints across the entire body by solving a constrained optimization problem (typically a quadratic program, QP).75% similarVerifiedModel Predictive Control (MPC) optimizes future control sequences within a receding horizon, and in recent years has achieved notable success in real-time motion control of quadruped robots.71% similarUnverified宇树B2采用的控制架构融合MPC负责中层步态规划与神经网络控制器处理底层快速扰动响应的双层架构69% similarUnverifiedThe WBC approach requires real-time maintenance of the robot's complete dynamic model, including the mass matrix, Coriolis forces, gravity compensation terms, and ground contact constraints, with high computational cost and sensitivity to modeling errors.65% similar
