Modeling and optimal control of dual stage cable suspended robot considering the cables’ elasticity using State Dependent Riccati Equation (SDRE) approach

Journal of Vibration and Control
In this paper, the modeling of a new two-stage cable robot is developed, while the flexibility of the cables is also considered. The performance of this robot is controlled using a strong nonlinear optimal control based on state dependent Riccati ...

Analysis of SDC matrices for successfully implementing the SDRE scheme

Automatica, 2013
Abstract The state-dependent Riccati equation (SDRE) approach for stabilization of nonlinear affine systems was recently reported to be effective in many practical applications; however, there is no guideline on the construction of state-dependent coefficient (SDC) matrix when the SDRE solvability condition is violated, which may result in the SDRE ...

SDRE-Based Estimation and Control: A Comparative Study of Kalman and H-infinity Filters in Nonlinear Systems

International Conference on Control, Decision and Information Technologies
This paper presents a comparative analysis of state estimation techniques, SDRE-based Kalman and H-infinity filters, ${\mathcal{H}_\infty }$, within the context of nonlinear systems controlled via the State-Dependent Riccati Equation (SDRE) framework ...

Cooperative Control of Underwater Manipulators Based on the SDRE Method

2021 International Russian Automation Conference (RusAutoCon), 2021
the paper exams the problem of coordinated control of underwater manipulators when moving a load with a concentrated mass along a given trajectory. The control approach is based on the representation of nonlinear models of manipulator dynamics in the linear state-space form with state-dependent coefficients (SDC form).

SDRE-based cooperative target tracking problem

2015 34th Chinese Control Conference (CCC), 2015
In the terminal guidance phase, the implementation of advanced guidance law is required of the relative motion information. In this paper, the estimation problem of relative motion information between an interceptor and a target is considered separately based on the classical extended Kalman filtering (EKF) and state-dependent Riccati equation (SDRE ...

Reconfigurable Dynamic Control Allocation with SDRE As a FTFC for NASA GTM Design

American Control Conference, 2021
There are too many control surfaces for over-actuated aircraft. The coordination and distribution of the efforts between these control surfaces is a problem, and this problem can be solved by Control Allocation (CA).

Barrier Function-Based SDRE Control for Nonlinear Systems with State Constraints

American Control Conference, 2021
Many real life systems operate in restricted state space. This study presents a new controller design technique for solving nonlinear regulator problems under the state dependent Riccati equation (SDRE) framework for systems with state constraints.

Attitude control of a satellite using the SDRE method

Proceedings of the 1997 American Control Conference (Cat. No.97CH36041), 1997
Examines the use of nonlinear regulation for attitude control of a satellite controlled by internal momentum rotors. Specifically, the nonlinear method using the state dependent Riccati equation (SDRE) developed by Cloutier, D'Souza, and Mracek (1996) is applied and examined under numerical simulations.
