Wind response characteristics of horizontal axis wind turbines [PDF]

, 1981
It was the objective of the work reported here, and in the companion paper 1 . A broader examination of wind turbine dynamic response to turbulence, and attempts to ascertain the features of turbulence that wind turbines are most sensitive to were made.

Direct yaw moment control of eight-wheeled distributed drive electric vehicles based on super-twisting sliding mode control

Frontiers in Mechanical Engineering
This paper proposed a novel direct yaw moment control (DYC) system to enhance vehicle stability and handling performance in various driving conditions and overcome the chattering problem of traditional sliding mode control. Accordingly, a DYC strategy is

Coordinated Control of Trajectory Tracking and Lateral Stability for Distributed Electric-Driven Buses

World Electric Vehicle Journal
To resolve the inherent coupling conflict between trajectory tracking and lateral stability in distributed electric drive buses, this paper proposes a hierarchical cooperative control framework. A simplified two-degree-of-freedom (2-DOF) vehicle model is
