The direct yaw-moment control based on adaptive fuzzy LQR for distributed drive electric vehicles

open access: yesAdvances in Mechanical Engineering
This paper introduced a hierarchical control strategy for direct yaw moment (DYC) to enhance the handling and stability of distributed drive electric vehicles (DDEVs) at medium to high speeds. The upper controller entailed a speed-following PI controller

Trajectory Tracking and Stability Control of Distributed-Drive Heavy Trucks on High-Speed Curves with Large Curvature

open access: yesWorld Electric Vehicle Journal
To address the difficulty of balancing trajectory-tracking accuracy and yaw stability for distributed-drive four-axle heavy trucks under high-speed and large-curvature cornering conditions, this paper proposes a hierarchical cooperative control strategy.

The response of a 38m horizontal axis teetered rotor to yaw [PDF]

open access: yes
Recent tests on the 38m Mod-0 100 kW horizontal axis experimental wind turbine yielded quantative data on the teeter response of a rotor to yaw. The test results indicate that yaw rates as high as 5 deg/s could be used in emergency situations to unload ...

A real-time, dual processor simulation of the rotor system research aircraft [PDF]

open access: yes
A real-time, man-in-the loop, simulation of the rotor system research aircraft (RSRA) was conducted. The unique feature of this simulation was that two digital computers were used in parallel to solve the equations of the RSRA mathematical model.
