Sideslip angle, yaw rate, and vehicle velocity are essential for intelligent vehicle control. Since these vehicle states are not measured directly, some Kalman-based approaches have been developed to estimate these states using in-vehicle sensors. However, the existing studies seldom account for the influence of sensor data loss on estimation accuracy. In addition,the process and measurement noise change during the estimation process because of the various driving conditions. To address these problems, an expectation-maximization robust extended Kalman filter (EMREKF) is proposed. Firstly, a robust extended Kalman filter (REKF) is developed to deal with the impact of missing measurements. Then, an improved expectation maximization (EM) algorithm that considers data loss is presented to update the noise parameter of the REKF dynamically. Finally,the improved EM is fused with the REKF to form the EMREKF to estimate vehicle state. The experimental results demonstrate that the EMREKF outperforms EKF, REKF, and maximum correntropy criterion EKF for various degrees of data loss and the proposed algorithm has a strong adaptive ability to different driving conditions.

Journal of Zhejiang University-Science A(Applied Physics & Engineering) 2008年第11期9卷 1531-1538页

This paper presents a disturbance rejection scheme for walking robots under unknown external forces and moments. The disturbance rejection strategy, which combines the inverse dynamics control with the acceleration projection onto the ZMP (zero moment point)-plane, can ensure the overall dynamic stability of the robot during tracking the pre-computed trajectories. Under normal conditions, i.e., the system is dynamically balanced, a primary inverse dynamics control is utilized. In the case that the system becomes unbalanced due to external disturbances, the acceleration projection control (APC) loop, will be activated to keep the dynamic stability of the walking robot through modifying the input torques. The preliminary experimental results on a robot leg demonstrate that the proposed method can actually make the robot keep a stable motion under unknown external perturbations.

Skeletal muscle plays a significant role in both local and systemic energy metabolism. The current investigation aims to explore the role of the Bambi gene in skeletal muscle, focusing on its implications for muscle hypertrophy and systemic metabolism. We hypothesize that skeletal muscle-specific deletion of Bambi induces muscle hypertrophy, improves metabolic performance, and activates thermogenic adipocytes via the reprogramming of progenitor of i WAT, offering potential therapeutic strategies for metabolic syndromes. Leveraging the Chromatin immunoprecipitation(ChIP)-seq and bioinformatics analysis, Bambi gene is shown to be a direct target of HIF2α, which is further confirmed by ChIP-qPCR and promoter luciferase assay. Skeletal muscle-specific Bambi deletion led to significant muscle hypertrophy and improved metabolic parameters, even under high-fat diet conditions. This deletion induced metabolic reprogramming of stromal vascular fractions(SVFs) into thermogenic adipocytes, contributing to systemic metabolic improvements, potentially through the secretory ***, mice with skeletal muscle-specific Bambi deletion demonstrate resistance to high-fat diet-induced metabolic disorders, highlighting a potential therapeutic pathway for metabolic syndrome management. Thus, skeletal muscle-specific deletion of Bambi triggers muscle growth, enhances metabolic performance, and activates thermogenic adipocytes. These findings suggest Bambi as a novel therapeutic target for metabolic syndromes, providing new insights into the interaction between muscle hypertrophy and systemic metabolic improvement. The study underscores the potential of manipulating muscle physiology to regulate whole-body metabolism, offering a novel perspective on treating metabolic disorders.
