A Comparative Study of Nonlinear MPC and Differential-Flatness-Based Control for Quadrotor Agile Flight [PDF]

open access: yesIEEE Transactions on robotics, 2021
Accurate trajectory-tracking control for quadrotors is essential for safe navigation in cluttered environments. However, this is challenging in agile flights due to nonlinear dynamics, complex aerodynamic effects, and actuation constraints.

Quadcopter Tracking Using Euler-Angle-Free Flatness-Based Control [PDF]

open access: yesEuropean Control Conference, 2022
Quadcopter trajectory tracking control has been extensively investigated and implemented in the past. Available controls mostly use the Euler angle standards to describe the quadcopter’s rotational kinematics and dynamics.

A Flatness‐Based Controller for the Stabilization of the Inverted Pendulum [PDF]

open access: yesMathematical Problems in Engineering, 2011
We propose a flatness based approach for controlling the inverted pendulum cart system, under the assumption that the pendulum state is always located on a vicinity of its unstable equilibrium point. This is achieved by representing the original system, as a chain of integrators with an additive nonlinear state dependent perturbation.

A Control Concept for Battery Emulators Using a Reference Governor With a Variable PT1-Element for Constraint Handling

open access: yesIEEE Open Journal of Industry Applications, 2022
This paper presents a method for highly dynamic nonlinear control of DC-DC converters with constraints used in battery emulators. Controlling this system is particularly challenging as the connected units-under-test often behave like constant power loads

Decoupling Predictive Control of Strip Flatness and Thickness of Tandem Cold Rolling Mills Based on Convolutional Neural Network

open access: yesIEEE Access, 2020
The control system regarding flatness and thickness of the strip in tandem cold rolling mill is generally multivariate, non-linear, and strong-coupling.
