Constrained nonlinear optimal control: a converse HJB approach [PDF]
, 1996 Extending the concept of solving the Hamilton-Jacobi-Bellman (HJB) optimization equation backwards [2], the so called converse constrained optimal control problem is introduced, and used to create various classes of nonlinear systems for which the ...

Nonlinear Receding-Horizon Control of Rigid Link Robot Manipulators
, 2005 The approximate nonlinear receding-horizon control law is used to treat the trajectory tracking control problem of rigid link robot manipulators. The derived nonlinear predictive law uses a quadratic performance index of the predicted tracking error and ...

A comparative study of several control techniques applied to a boost converter [PDF]
, 2006 In this paper a comparison among three control strategies is presented, with application to a boost DC-DC converter. The control strategies are developed on the switched boost circuit model and validated on the nonlinear model by use of simulations.

Global Stabilization of Triangular Systems with Time-Delayed Dynamic Input Perturbations
, 2018 A control design approach is developed for a general class of uncertain strict-feedback-like nonlinear systems with dynamic uncertain input nonlinearities with time delays. The system structure considered in this paper includes a nominal uncertain strict-

Estimation of nonlinear surface pressure characteristics of aerofoil: A 0-1 test approach
AIP Advances, 2019 We investigate the nonlinear behaviour of the surface flow over a two-dimensional NACA 2415 airfoil undergoing turbulent inflow having 8.46% TI at Re=3.01×105 using the 0-1 test for chaos.

A posteriori error estimates of spectral method for nonlinear parabolic optimal control problem
Journal of Inequalities and Applications, 2018 In this paper, we investigate the spectral approximation of optimal control problem governed by nonlinear parabolic equations. A spectral approximation scheme for the nonlinear parabolic optimal control problem is presented. We construct a fully discrete

Optimal Aggressive Constrained Trajectory Synthesis and Control for Multi-Copters
Aerospace, 2022 In this paper, we propose a novel time and control effort optimal aggressive trajectory synthesis and control design methodology. The trajectory synthesis is a modified minimum snap design but with specific position and orientation constraints on a multi-

, 2017 Nonlinear behavior is the general rule in physics and nature. Linear models, obtained by linearization or identification, are in general crude approximations of nonlinear behaviors of plants in the neighbourhood of an operating point. However, in many cases such as startup, shutdown, or important transient regimes, study of batch and fed-batch ...
