Chatter vibration highly limits the accuracy and the material removal rate of numerical control (NC) machining operations. In this paper, an adaptive spindle speed selection method, based on an analysis using the semi-discretization method, is proposed to avoid and minimize chatter vibration in high-precision NC machining. Moreover, the proposed method is robust to modeling uncertainty and changing...
The productivity of numerical control (NC) machining is highly limited by the occurrence of chatter vibration. Chatter stability analyses are widely studied to predict chatter vibration. However, these analyses often fail to provide reliable prediction results because the parameters in the vibration model are sensitive to identification errors, mechanical deterioration and thermal changes. On the...
Tire force distribution is an important topic in motion control of electric vehicles. For years, many researchers have focused on optimal distribution by minimizing a certain cost function. However, no effort has been paid to the stability analysis of tire force distribution theoretically. Let the actuators (in-wheel-motors and steering motors) be the local agents, the electric vehicle can be seen...
In order to improve motion control performance of electric vehicles (EVs), In-Wheel Motor (IWM) is the most preferred electric motor arrangement. Our research group has proposed Wireless In-Wheel Motor (W-IWM) concept to solve some technical problems of an IWM, which are reliability and safety issues of power and signal wires. In this research, we did a stability analysis of Series-Series compensated...
This paper presents a method for using lateral tire force sensors to estimate vehicle sideslip angle and to improve vehicle stability of in-wheel-motor-driven electric vehicles (IWM-EVs). Considering that the vehicle motion is governed by tire forces, lateral tire force measurements give practical benefits in estimation and motion control. To estimate the vehicle sideslip angle, a state observer derived...
