On Vehicle Stabilization Under Saturation Constraints by Linear Quadratic Regulator

Enhancement of Articulated Heavy Vehicle Stability by Optimal Linear Quadratic Regulator (LQR) Controller of Roll-yaw Dynamics

Non-linear characteristic of tire forces is the main cause of vehicle lateral dynamics instability, while direct yaw moment control is an effective method to recover the vehicle stability. In this paper, an optimal linear quadratic regulator (LQR) controller for roll-yaw dynamics to articulated heavy vehicles is developed. For this purpose, the equations of motion obtained by the MATLAB sof...

Control System Design for a Surface Effect Ship by Linear-Quadratic Regulator Method

In this paper, the main goal is to reduce the heave motion between a surface effect ship (SES) and a wind turbine in order to safely transfer equipment and person to SES. For this purpose, an LQR control system is designed to damp the vertical motion of the surface effect ship in critical sea states including high-frequency and high amplitude regular waves as well as high frequency irregular wa...

Constraints on Quadratic Curves Under Perspective Projection

In this paper we address the problem of 3D-location estimation based on quadratic-curved features. It is assumed that the true size and true shape of a feature in object space are known, along with its perspective projection in the image plane. In our approach, we decompose the 3D-location-estimation problem into a concatenated process of SD-orientation estimation and 3D-position estimation. In...
