On the Use of Low-Order Riccati-Equations in the Design of a Class of Feedback Controllers and State Estimators [PDF]

open access: yesModeling, Identification and Control, 1980
This paper describes a method for designing optimal feedback controllers with stability requirements using low-order Riccati equations. For originally stable systems the Riccati equation will be of first or second order, depending upon whether the ...

Transform of Riccati equation of constant coefficients through fractional procedure [PDF]

open access: yes, 2003
We use a particular fractional generalization of the ordinary differential equations that we apply to the Riccati equation of constant coefficients. By this means the latter is transformed into a modified Riccati equation with the free term expressed as ...

Linear Quadratic Stochastic Differential Games: Open-Loop and Closed-Loop Saddle Points [PDF]

open access: yes, 2014
In this paper, we consider a linear quadratic stochastic two-person zero-sum differential game. The controls for both players are allowed to appear in both drift and diffusion of the state equation.

Approximation of Solutions of Riccati Equations [PDF]

open access: yesSIAM Journal on Control and Optimization, 2005
This paper deals with two interrelated issues. One is an invariant subspace approach to finding solutions for the algebraic Riccati equation for a class of infinite dimensional systems. The second is approximation of the solution of the algebraic Riccati equation by finite dimensional approximants.

Series Expansion and Fourth-Order Global Padé Approximation for a Rough Heston Solution

open access: yesMathematics, 2020
The rough Heston model has recently been shown to be extremely consistent with the observed empirical data in the financial market. However, the shortcoming of the model is that the conventional numerical method to compute option prices under it requires

Maximal imaginery eigenvalues in optimal systems [PDF]

open access: yesModeling, Identification and Control, 1991
In this note we present equations that uniquely determine the maximum possible imaginary value of the closed loop eigenvalues in an LQ-optimal system, irrespective of how the state weight matrix is chosen, provided a real symmetric solution of the ...

New Solitary-Wave Solutions of the Van der Waals Normal Form for Granular Materials via New Auxiliary Equation Method

open access: yesMathematics, 2022
In this paper, we use general Riccati equation to construct new solitary wave solutions of the Van der Waals normal form, which is one of the most famous models for natural and industrial granular materials.

Numerical solution of nonlinear fractional Riccati differential equations using compact finite difference method [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization, 2022
This paper aims to apply and investigate the compact finite difference methods for solving integer-order and fractional-order Riccati differential equations. The fractional derivative in the fractional case is described in the Caputo sense.

On Riccati Equations in Banach Algebras [PDF]

open access: yesSIAM Journal on Control and Optimization, 2011
Let $R$ be a commutative complex Banach algebra with the involution $\cdot ^\star$ and suppose that $A\in R^{n\times n}$, $B\in R^{n\times m}$, $C\in R^{p\times n}$. The question of when the Riccati equation $$ PBB^\star P-PA-A^\star P-C^\star C=0 $$ has a solution $P\in R^{n\times n}$ is investigated.

New sub-equation method to construct solitons and other solutions for perturbed nonlinear Schrödinger equation with Kerr law nonlinearity in optical fiber materials

open access: yesJournal of Ocean Engineering and Science, 2019
In a previous work, Zayed and Al-Nowehy have applied the Riccati equation mapping method combined with the generalized extended (G′/G)-expansion method and found new exact solutions of the nonlinear KPP equation.
