Two approximate solutions to HJI equation via state dependent Riccati equation

2001 European Control Conference (ECC), 2001
One of the most important problems in nonlinear H ∞ control is how to solve its main equation i.e., HJI equation. We propose two new and efficient methods to solve this problem in state feedback set up, based on state dependent Riccati equation. Superiority of these suggested methods in comparison with some methods proposed before is shown through ...

Suboptimal control of a 3 dof helicopter with state dependent riccati equations

2017 XXVI International Conference on Information, Communication and Automation Technologies (ICAT), 2017
The paper presents the application of State Dependent Riccati Equation (SDRE) based optimal controller design for nonlinear systems. Optimal controller is designed in local sense to minimize a given quadratic performance index, leading to well-known Linear Quadratic Regulator (LQR) problem and the optimal controller is updated at each sampling time to ...

Ensuring stability of state-dependent Riccati equation controllers via satisficing

Proceedings of the 41st IEEE Conference on Decision and Control, 2002., 2003
Controls based on solutions to the state-dependent Riccati equation (SDRE) have been shown to offer high performance, but they suffer from unproven stability properties. This paper combines SDRE with satisficing, a novel clf-based approach which analytically guarantees stability.

Exponential nonlinear observer based on the differential state-dependent Riccati equation

International Journal of Automation and Computing, 2012
This paper presents a novel nonlinear continuous-time observer based on the differential state-dependent Riccati equation (SDRE) filter with guaranteed exponential stability. Although impressive results have rapidly emerged from the use of SDRE designs for observers and filters, the underlying theory is yet scant and there remain many unanswered ...

State-dependent Riccati equation techniques: an overview

Proceedings of the 1997 American Control Conference (Cat. No.97CH36041), 1997
State-dependent Riccati equation (SDRE) techniques are rapidly emerging as general design methods which provide a systematic and effective means of designing nonlinear controllers, observers, and filters. This paper provides an overview of several SDRE design techniques including SDRE nonlinear regulation, SDRE nonlinear H/sub /spl infin//, SDRE ...

Design of a Class of Nonlinear Controllers via State Dependent Riccati Equations

IEEE Transactions on Control Systems Technology, 2004
In this brief, infinite-horizon nonlinear regulation of second-order systems using the State Dependent Riccati Equation (SDRE) method is considered. By a convenient parametrization of the A(x) matrix, the state-dependent algebraic Riccati equation is solved analytically.

Online solution of state dependent Riccati equation for nonlinear system stabilization

Proceedings of the 2010 American Control Conference, 2010
A number of computational methods have been proposed in the literature for synthesizing nonlinear control based on state-dependent Riccati equation (SDRE). Most of these methods are numerically complex or depend on correct initial conditions. This paper presents a new and computationally efficient online method for the design of stabilizing control for

Controller design of cooperative manipulators using state-dependent Riccati equation

Robotica, 2017
SUMMARYThis study examined the use of a state-dependent Riccati equation (SDRE) for controller design and analysis of cooperative manipulators. The connection of end-effectors when holding an object imports constraint and complexity into the problem.
