An effective proportional-double derivative-linear quadratic regulator controller for quadcopter attitude and altitude control

open access: yesAutomatika, 2021
A quadcopter control system is a fundamentally difficult and challenging problem because its dynamics modelling is highly nonlinear, especially after accounting for the complicated aerodynamic effects.

Linear Quadratic Gaussian Regulator for the Nonlinear Observer-Based Control of a Dynamic Base Inverted Pendulum [PDF]

open access: yesINCAS Bulletin, 2021
The inverted pendulum is a non-linear control problem permanently tending towards instability. The main aim of this study is to design a controller capable enough to work within the given conditions while also keeping the pendulum erect given the ...

On adaptive Linear–Quadratic regulators [PDF]

open access: yesAutomatica, 2020
Performance of adaptive control policies is assessed through the regret with respect to the optimal regulator, which reflects the increase in the operating cost due to uncertainty about the dynamics parameters. However, available results in the literature do not provide a quantitative characterization of the effect of the unknown parameters on the ...

Constrained linear quadratic regulation [PDF]

open access: yesIEEE Transactions on Automatic Control, 1998
Summary: This paper is a contribution to the theory of the infinite-horizon Linear Quadratic Regulator (LQR) problem subject to inequality constraints on the inputs and states, extending an approach first proposed by Sznaier and Damborg. A solution algorithm is presented, which requires solving a finite number of finite-dimensional positive definite ...
