A Newton Algorithm for Implementation of SDRE Controllers

open access: yesAIAA Guidance, Navigation, and Control Conference and Exhibit, 2005
State-Dependent-Riccati-Equation (SDRE) is a recently introduced control method that attempts to establish a systematic procedure for dealing with a general class of nonlinear systems. Some of the known limitations of the SDRE techniques are the high computational load due to recurrent Riccati equation and the lack of an a priori global stability ...

Fast real-time SDRE controllers using neural networks

ISA Transactions, 2021
This paper describes the implementation of fast state-dependent Riccati equation (SDRE) control algorithms through the use of shallow and deep artificial neural networks (ANN). Several ANNs are trained to replicate an SDRE controller developed for a satellite attitude dynamics simulator (SADS) to display the technique's efficacy. The neural controllers

Advanced Control: The Augmented SDRE Technique

open access: yes, 2010
This chapter introduces the augmented state-dependent Riccati equation (SDRE) technique for the advanced control of the tandem cold metal rolling process. The advantages of the SDRE method when compared to conventional control are presented. The characteristics of several other advanced control methods are included for evaluation in light of the ...

Manipulator path control using SDRE

Proceedings of the 2000 American Control Conference. ACC (IEEE Cat. No.00CH36334), 2000
A controller synthesis based on state dependent Riccati equation methods is presented. The methodology is applied to the path control of a slow moving robot manipulator, for the purpose of method validation. Due to hardware limitations, not all the manipulator joints were controlled, and the resulting gains are obtained off-line using numerical ...

SDRE-Based Suboptimal Controller for Manipulator Control

2019 12th International Workshop on Robot Motion and Control (RoMoCo), 2019
The paper presents modelling and control of a robotic arm. To solve the control problem, the state-dependent Riccati equation (SDRE) method is applied. As a new contribution, the paper deals with state-dependent parametrization as an effective modelling of robot manipulator and shows how to modify classical form of the SDRE method to reduce ...
