Differential flatness-based pseudospectral optimal control of six-degrees-of-freedom aircraft and its issues
R. Sandeepkumar,Ranjith Mohan +1 more
TL;DR: A flatness-based nonlinear model predictive controller (NMPC) for a 6DoF aircraft to improve computational time and pseudospectral knots are explored in the paper, which improves sparsity and numerical conditioning of flathood-based optimal control problems.

Flatness and defect of non-linear systems: introductory theory and examples
TL;DR: In this paper, the authors introduce flat systems, which are equivalent to linear ones via a special type of feedback called endogenous feedback, which subsumes the physical properties of a linearizing output and provides another nonlinear extension of Kalman's controllability.

Minimum snap trajectory generation and control for quadrotors
Daniel Mellinger,Vijay Kumar +1 more
TL;DR: An algorithm is developed that enables the real-time generation of optimal trajectories through a sequence of 3-D positions and yaw angles, while ensuring safe passage through specified corridors and satisfying constraints on velocities, accelerations and inputs.

Direct trajectory optimization by a Chebyshev pseudospectral method
Fariba Fahroo,I. Michael Ross +1 more
TL;DR: A Chebyshev pseudospectral method is presented in this paper for directly solving a generic optimal control problem with state and control constraints and yields more accurate results than those obtained from the traditional collocation methods.

A modified quadratic cost problem and feedback stabilization of a linear system
Wook Hyun Kwon,A. E. Pearson +1 more
TL;DR: In this article, a feedback control law for linear systems based on a minimum energy regulator problem with fixed terminal constraints on the state was considered and a modification of this control law was shown to be asymptotically stable.
