Optimal control theory based design of elasto-magnetic metamaterial [PDF]
, 2017 A method to design a new type of metamaterial is presented. A two-step strategy to define an optimal long-range force distribution embedded in an elastic support to control wave propagation is considered. The first step uses a linear quadratic regulator

Event-based LQR with integral action [PDF]
Proceedings of the 2014 IEEE Emerging Technology and Factory Automation (ETFA), 2014 In this paper, a state-feedback linear-quadratic regulator (LQR) is proposed for event-based control of a linear system. An interesting property of LQRs is that an optimal response of the system can be obtained in accordance to some specifications, like the actuator limits.

MIMO PID Controller Tuning Method for Quadrotor Based on LQR/LQG Theory [PDF]
, 2019 In this work, a new pre-tuning multivariable PID (Proportional Integral Derivative) controllers method for quadrotors is put forward. A procedure based on LQR/LQG (Linear Quadratic Regulator/Gaussian) theory is proposed for attitude and altitude ...

About the loss of robustness of the LQG/LTR compensator [PDF]
INCAS BulletinIt is known that the optimal LQR regulator (Linear Quadratic Regulator) with full state feedback has remarkable robustness properties, defined by gain margins of (1/2, ) and phase of at least ± 60 degrees.

A Comparative Study of LQR and Sliding Control for Ball and Beam System [PDF]
Robotica & ManagementIn this paper, we will survey two controllers, a linear control (LQR) and sliding mode control (SMC) on a central axis ball and beam (B&B) – a single input-multiple output (SIMO) system through simulation and experiment.

LQR controller design for quad‐rotor helicopters [PDF]
The Journal of Engineering, 2019 This paper presents an analysis and performance of a LQR control algorithm for quadrotor helicopters. For a successful analysis, first the dynamic model has been developed for the quadcopter and then the controller was designed, tuned, and tested. In tuning the LQR, much attention was given to the feedback gain matrix (K).

Speed Dependent Gain Scheduled LQI based Path Following Control System Design for Automated Vehicles
Gazi Üniversitesi Fen Bilimleri Dergisi, 2019 Automated path following is one of the major problem in automated vehicle control. Automated vehicle should follow the desired path to minimize the lateral deviation from the path while traveling at the desired speed. In this paper, LQI control method is

Data-Driven LQR Control Design [PDF]
IEEE Control Systems Letters, 2019 This paper presents a data-driven solution to the discrete-time infinite horizon LQR problem. The state feedback gain is computed directly from a batch of input and state data collected from the plant. Simulation examples illustrate the convergence of the proposed solution to the optimal LQR gain as the number of Markov parameters tends to infinity ...

LQR Design under Stability Constraints
IFAC-PapersOnLine, 2020 Abstract The solution of classic discrete-time, finite-horizon linear quadratic regulator (LQR) problem is well known in literature. By casting the solution to be a static state-feedback, we propose a new method that trades off low LQR objective value with closed-loop stability.
