Nonlinear Suboptimal Guidance Law With Impact Angle Constraint: An SDRE-Based Approach

IEEE Transactions on Aerospace and Electronic Systems, 2020
In this article, a guidance law with impact angle constraint is developed using the state-dependent Riccati equation (SDRE) technique. First, the nonlinear guidance dynamics consisting of line-of-sight (LOS) angle rate and error is formulated under a ...

SDRE AUTOPILOT FOR DUAL CONTROLLED MISSILES

IFAC Proceedings Volumes, 2007
Abstract The SDRE technique is used to develop an autopilot design for a dual controlled (tail and canard) missile. Dual control missiles can have difficulty achieving high angles of attack and thus high levels of lateral acceleration because the control surfaces move together to achieve quick responses but in steady state the deflections can be ...

On Factorization of the Nonlinear Drift Term for SDRE Approach

IFAC Proceedings Volumes, 2011
Abstract This study presents necessary and sufficient conditions for the existence of a constant matrix A that satisfies A x = f , ( A, B ) is stabilizable and ( A, C ) is observable (resp., detectable), where x and f are two constant vectors with x ≠ 0 , while B and C are two constant matrices with approximate dimension. The conditions

Neural Network Model for Constructing Feedback in Nonlinear Control Systems Based on Asymptotic Methods and the SDRE Approach

2024 International Russian Smart Industry Conference (SmartIndustryCon)
Here the problem of nonlinear control system stabilization is considered. By presenting the model of a nonlinear control system with a parameter that changes over a certain interval in a formally linear form with state dependent matrices and by ...

QUASI-OPTIMUM CONTROL AND THE SDRE METHOD

IFAC Proceedings Volumes, 2007
Abstract Two suboptimum control methods are compared. One is the currently popular state-dependent Riccati equation (SDRE) method and the other is based on the quasi-optimum control method developed by the author in the 1960's. Both methods are applied to a nonlinear dynamic system with a quadratic performance criterion.

A Note on SDRE Control Applied in the Fermentation Reactor

International Review of Mechanical Engineering (IREME), 2019
In this work, the dynamic behaviour of a bioreactor model designed for fermentation processes is investigated. The production of ethanol is presented analyzing the temperature of the fermenter, which is controlled by the flow of the cooling fluid (water) which passes through the jacket of the fermenter.

Multi-timescale SDRE control for an unmanned helicopter

2010 2nd International Conference on Advanced Computer Control, 2010
This paper proposes an improved state-dependent Riccati equation (SDRE) attitude control approach which is applied to an unmanned helicopter (UMH) through a multi-timescale structure. To deal with inherent unstable internal dynamics, the flapping and rotational dynamics of the helicopter are organized into a two-timescale nonlinear model.

A design of servo controller with SDRE for nonlinear systems

Proceedings of the 41st SICE Annual Conference. SICE 2002., 2003
In this paper, we propose a new servo controller design method for nonlinear systems, which can be considered as an extended version of the Smith-Davison type servo controller. The control input of the controller is given by computing the Riccati equation dependent on the state, which is called the SDRE (state dependent Riccati equation), repeatedly at
