A Unified Framework for Online Data-Driven Predictive Control with Robust Safety Guarantees

no code implementations29 Jun 2023 Amin Vahidi-Moghaddam, Kaian Chen, Kaixiang Zhang, Zhaojian Li, Yan Wang, Kai Wu

Despite great successes, model predictive control (MPC) relies on an accurate dynamical model and requires high onboard computational power, impeding its wider adoption in engineering systems, especially for nonlinear real-time systems with limited computation power.

Extended Neighboring Extremal Optimal Control with State and Preview Perturbations

no code implementations7 Jun 2023 Amin Vahidi-Moghaddam, Kaixiang Zhang, Zhaojian Li, Xunyuan Yin, Ziyou Song, Yan Wang

In this work, an extended NE (ENE) framework is developed to systematically adapt the nominal control to both state and preview perturbations.

Physics-Augmented Data-EnablEd Predictive Control for Eco-driving of Mixed Traffic Considering Diverse Human Behaviors

no code implementations2 Jun 2023 Dongjun Li, Kaixiang Zhang, Haoxuan Dong, Qun Wang, Zhaojian Li, Ziyou Song

In this paper, we employ a data-enabled predictive control (DeePC) scheme to address the eco-driving of mixed traffic flows with diverse behaviors of human drivers.

O2RNet: Occluder-Occludee Relational Network for Robust Apple Detection in Clustered Orchard Environments

no code implementations8 Mar 2023 Pengyu Chu, Zhaojian Li, Kaixiang Zhang, Dong Chen, Kyle Lammers, Renfu Lu

One key technology to fully enable efficient automated harvesting is accurate and robust apple detection, which is challenging due to complex orchard environments that involve varying lighting conditions and foliage/branch occlusions.

Dimension Reduction for Efficient Data-Enabled Predictive Control

no code implementations7 Nov 2022 Kaixiang Zhang, Yang Zheng, Chao Shang, Zhaojian Li

In this letter, we propose a simple yet effective singular value decomposition (SVD) based strategy to reduce the optimization problem dimension in data-enabled predictive control (DeePC).

Data-Enabled Predictive Control for Fast Charging of Lithium-Ion Batteries with Constraint Handling

no code implementations26 Sep 2022 Kaixiang Zhang, Kaian Chen, Xinfan Lin, Yusheng Zheng, Xunyun Yin, Xiaosong Hu, Ziyou Song, Zhaojian Li

Fast charging of lithium-ion batteries has gained extensive research interests, but most of existing methods are either based on simple rule-based charging profiles or require explicit battery models that are non-trivial to identify accurately.

Privacy-Preserving Data-Enabled Predictive Leading Cruise Control in Mixed Traffic

no code implementations22 May 2022 Kaixiang Zhang, Kaian Chen, Zhaojian Li, Jun Chen, Yang Zheng

Data-driven predictive control of connected and automated vehicles (CAVs) has received increasing attention as it can achieve safe and optimal control without relying on explicit dynamical models.

Cloud-Assisted Nonlinear Model Predictive Control for Finite-Duration Tasks

no code implementations20 Jun 2021 Nan Li, Kaixiang Zhang, Zhaojian Li, Vaibhav Srivastava, Xiang Yin

In this paper, we propose a novel cloud-assisted model predictive control (MPC) framework in which we systematically fuse a cloud MPC that uses a high-fidelity nonlinear model but is subject to communication delays with a local MPC that exploits simplified dynamics (due to limited computation) but has timely feedback.
