A LQR Optimal Method to Control the Position of an Overhead Crane [PDF]

open access: yesIAES International Journal of Robotics and Automation (IJRA), 2014
In this paper, a LQR (Linear Quadratic Regulation) optimal method is implemented to control position of an overhead carne. To do this, a tracking formulation of LQR is developed and applied to the system. Hence the dynamic model of the overhead crane is presented, the dynamic of the actuator motor of the trolley is considered.

Determination of LQR weights by Bayesian optimization method using multiple earthquake waves

open access: yesIECON 2020 The 46th Annual Conference of the IEEE Industrial Electronics Society, 2020
An active structural-control strategy has been widely studied to improve the control performance. Most studies used the linear quadratic-regulator (LQR) method to design the state-feedback controller. The LQR method requires to tune many weights in the cost function to design the controller.

MIMO PID Controller Tuning Method for Quadrotor Based on LQR/LQG Theory

open access: yesRobotics, 2019
In this work a new pre-tuning multivariable PID controllers method for quadrotors is put forward. A procedure based on LQR/LQG theory is proposed for attitude and altitude control. With the aim of analyzing performance and robustness of the proposed method, a non-linear mathematical model of the DJI-F450 quadrotor is employed, where rotors dynamics ...

Distributed LQR Methods for Networks of Non-Identical Plants [PDF]

open access: yes2018 IEEE Conference on Decision and Control (CDC), 2018
Two well-established complementary distributed linear quadratic regulator (LQR) methods applied to networks of identical agents are extended to the non-identical dynamics case. The first uses a top-down approach where the centralized optimal LQR controller is approximated by a distributed control scheme whose stability is guaranteed by the stability ...
