Direct Yaw Moment Control for Distributed Drive Electric Vehicles Based on Hierarchical Optimization Control Framework

Mathematics
Direct yaw moment control (DYC) can effectively improve the yaw stability of four-wheel distributed drive electric vehicles (4W-DDEVs) under extreme conditions, which has become an indispensable part of active safety control for 4W-DDEVs.

Aircraft control system [PDF]

, 1973
An aircraft control system is described which is particularly suited to rotary wing aircraft. Longitudinal acceleration and course rate commands are derived from a manual control stick to control translational velocity of the aircraft along a flight path.

Review on Direct Yaw Moment Control of Four-in-wheel Electric Vehicles

DEStech Transactions on Computer Science and Engineering, 2017
Due to the four-in-wheel electric vehicle (IEV) has a small volume and high power density, IEV has become an important development direction. Compared to traditional vehicles, IEVs increase the motion freedom with four driving source and IEV direct yaw moment control (DYC) becomes a burning issue.

Optimal torque distribution strategy of DDEV based on enhanced exponential sliding mode controller

Journal of Measurement Science and Instrumentation, 2023
A novel direct yaw-moment control scheme is proposed to improve the lateral stability of distributed-drive electric vehicles (DDEV). The scheme adopts a hierarchical control structure that consists of an upper controller and a lower controller.

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
