Transferable Latent-to-Latent Locomotion Policy for Efficient and Versatile Motion Control of Diverse Legged Robots

no code implementations22 Mar 2025 Ziang Zheng, Guojian Zhan, Bin Shuai, Shengtao Qin, Jiangtao Li, Tao Zhang, Shengbo Eben Li

We validate our approach through extensive simulations and real-world experiments, demonstrating that the pretrained latent-to-latent locomotion policy effectively generalizes to new robot entities and tasks with improved efficiency.

Predictive Lagrangian Optimization for Constrained Reinforcement Learning

no code implementations25 Jan 2025 Tianqi Zhang, Puzhen Yuan, Guojian Zhan, Ziyu Lin, Yao Lyu, Zhenzhi Qin, Jingliang Duan, Liping Zhang, Shengbo Eben Li

And we prove that the resulting optimal policy, achieved through alternating MFOCP and MGPL, aligns with the solution of the primal constrained RL problem, thereby establishing our equivalence framework.

An Explicit Discrete-Time Dynamic Vehicle Model with Assured Numerical Stability

no code implementations26 Nov 2024 Guojian Zhan, Qiang Ge, Haoyu Gao, Yuming Yin, Bin Zhao, Shengbo Eben Li

Subsequent to the validation process, we conduct comprehensive simulations comparing our proposed model with both kinematic models and existing dynamic models discretized through the forward Euler method.

Rocket Landing Control with Random Annealing Jump Start Reinforcement Learning

no code implementations21 Jul 2024 YuXuan Jiang, Yujie Yang, Zhiqian Lan, Guojian Zhan, Shengbo Eben Li, Qi Sun, Jian Ma, Tianwen Yu, Changwu Zhang

Our approach, called Random Annealing Jump Start (RAJS), is tailored for real-world goal-oriented problems by leveraging prior feedback controllers as guide policy to facilitate environmental exploration and policy learning in RL.

Canonical Form of Datatic Description in Control Systems

no code implementations4 Mar 2024 Guojian Zhan, Ziang Zheng, Shengbo Eben Li

This paper for the first time introduces the concept of canonical data form for the purpose of achieving more effective design of datatic controllers.

Bridging the Gap between Newton-Raphson Method and Regularized Policy Iteration

no code implementations11 Oct 2023 Zeyang Li, Chuxiong Hu, Yunan Wang, Guojian Zhan, Jie Li, Shengbo Eben Li

We also show that a modified version of regularized policy iteration, i. e., with finite-step policy evaluation, is equivalent to inexact Newton method where the Newton iteration formula is solved with truncated iterations.
