Research on Stability Control Algorithm of Distributed Drive Bus under High-Speed Conditions

World Electric Vehicle Journal, 2023
Aiming at the instability problem of a four-wheel independent drive electric bus under high-speed conditions, this paper first designs a vehicle yaw stability controller based on a linear two-degree-of-freedom model and a linear quadratic programming ...

Control Laws for a Dual-Spin Stabilized Platform [PDF]

, 2008
This paper describes two attitude control laws suitable for atmospheric flight vehicles with a steady angular momentum bias in the vehicle yaw axis. This bias is assumed to be provided by an internal flywheel, and is introduced to enhance roll and pitch ...

Control of sideslip and yaw rate in 4-wheel steering car using partial decoupling and individual channel design [PDF]

, 2003
This paper presents a new steering control structure for cars equipped with 4-wheel steering. This control structure is based on a simplified linear model of the lateral dynamics of such cars and aims to decouple the control of sideslip from the control ...

Trajectory Tracking of Autonomous Vehicle with the Fusion of DYC and Longitudinal–Lateral Control

Chinese Journal of Mechanical Engineering, 2019
The current research of autonomous vehicle motion control mainly focuses on trajectory tracking and velocity tracking. However, numerous studies deal with trajectory tracking and velocity tracking separately, and the yaw stability is seldom considered ...

The Wright Brothers: First Aeronautical Engineers and Test Pilots [PDF]

, 2003
Sir George Cayley invented the conventional configuration of the airplane at the turn of the 19th century. Otto Lilienthal realized that building a successful aircraft meant learning how to fly; he became the first hang glider pilot and also the first ...

High‐Speed Altitude Regulation With Neuromorphic Camera and Lightweight Embedded Computation

Advanced Intelligent Systems, EarlyView.
Neuromorphic cameras deliver rapid, high‐dynamic‐range sensing but overwhelm embedded processors at high speeds. This work presents a lightweight, optimized Lucas–Kanade optical flow method with parallelization, gyroscopic derotation, and adaptive event slicing.

Robust Yaw Moment Control for Vehicle Handling and Stability

SAE International Journal of Passenger Cars - Mechanical Systems, 2009
<div class="htmlview paragraph">This paper presents a robust controller design method for improving vehicle lateral stability and handling performance. In particular, the practical load variation will be taken into account in the controller synthesis process such that the controller can keep the vehicle lateral stability and handling performance ...

Vision‐Based Handover and Organization of Robotic Scrub Nurse for Seamless Surgical Flow

Advanced Intelligent Systems, EarlyView.
This study presents a pose estimation‐based robotic scrub nurse (PERSN) that assists surgical procedures by estimating the surgeon's hand position, orientation, and grasping state, along with the constraint‐based 6D pose of surgical instruments. User evaluations show that PERSN provides greater immediate usability and reduces physical demand compared ...
