Estimation of the Region of Attraction for State-Dependent Riccati Equation Controllers

Journal of Guidance, Control, and Dynamics, 2006
A new method for estimating a higher bound of the region of attraction of a nonlinear system is developed for state-dependent Riccati equation controller. The methodology can be applied to SDRE-controlled systems for improving the stability properties of such systems.

A State-Dependent Riccati Equation Approach to Atmospheric Entry Guidance

AIAA Guidance, Navigation, and Control Conference, 2010
This paper investigates the use of state-dependent Riccati equation control for closed-loop guidance of the hypersonic phase of atmospheric entry. Included are a discussion of the development of the state-dependent Riccati equations, their outgrowth from Hamilton-Jacobi-Bellman theory, a discussion of the closed-loop nonlinear system’s closed-loop ...

Controllability Issues in Nonlinear State-Dependent Riccati Equation Control

Journal of Guidance, Control, and Dynamics, 1998
Inthelastfewyears,algorithmsusingstate-dependentRiccatiequations (SDREs)havebeenproposedforsolving nonlinear control problems. Under state feedback, pointwise solutions of an SDRE must be obtained along the system trajectory. To ensure the control is well dee ned, global controllability and observability of state-dependent system factorizations are ...

STATE DEPENDENT DIFFERENTIAL RICCATI EQUATION FOR NONLINEAR ESTIMATION AND CONTROL

IFAC Proceedings Volumes, 2002
Abstract State-dependent Riccati equation (SDRE) methods for designing control algorithms and observers for nonlinear processes entail the use of algebraic Riccati equations. These methods have yielded a number of impressive results, however, they can be computationally quite intensive and thus far they have not yielded to those attempting to assess ...

Robust state dependent Riccati equation based guidance laws

Proceedings of the 2001 American Control Conference. (Cat. No.01CH37148), 2001
A robust state dependent Riccati equation based guidance/control is investigated in this study. In order to have a better design tool in terms of required interceptor accelerations, the target intercept geometry is formulated in a set of polar coordinates. With this formulation, we formulate a cost function with state dependent weights.

Missile Autopilot Design Based on State Dependent Riccati Equation

2009 International Asia Conference on Informatics in Control, Automation and Robotics, 2009
In this paper a control approach is presented for flight control system of a rigid body missile using both State Dependent Riccati Equation (SDRE) method and Fast Output Sampling (FOS) technique. The dynamics and kinematics for missile attitude stable problem are of typical nonlinear character.
