Stochastic properties of switched Riccati differential equations

2012 IEEE 51st IEEE Conference on Decision and Control (CDC), 2012
This paper studies switched Riccati differential equations, whose switching is driven by a Poisson-like random signal. First we show that the expected value of the escape time of a switched Riccati differential equation satisfies an integral equation and then give a sufficient condition for the equation to admit a unique solution.

Families of Solutions of Matrix Riccati Differential Equations

SIAM Journal on Control and Optimization, 1997
Summary: The J. C. Willems-Coppel-Shayman geometric characterization of solutions of the algebraic Riccati equation (ARE) is extended to asymmetric Riccati differential equations with time-varying coefficients. The coefficients do not need to satisfy any definiteness, periodicity, or system-theoretic condition. More precisely, given any two solutions \(

Hermitian Riccati differential equations

2003
This chapter is dedicated to the theory of Hermitian Riccati differential equations (HRDE), which are of importance in various fields of applications, as e.g., the linear quadratic optimal problem, differential games, differential geometry, fac­torization problems and spectral theory.

Differential and Difference Riccati Equations

1993
In this chapter, we study the main equations of the finite time optimal closed-loop linear-quadratic control problems, namely, the differential and difference Riccati equations, for both singularly perturbed and weakly coupled systems. A unique approach to the solutions of these Riccati equations is developed by performing the block diagonalization of ...

Riccati type matrix differential equations with jumps

2001 European Control Conference (ECC), 2001
The aim of this paper is to investigate some properties of the solutions of the differential Riccati-type systems arising in control problems for the time-varying linear systems with jumps. A major attention is paid to the stabilising solution of these systems.

Existence and comparison theorems for algebraic Riccati equations and Riccati differential and difference equations

Journal of Dynamical and Control Systems, 1996
The generalized Riccati differential equations \[ \dot W= -A^*W- WA- Q+ WSW- \Pi(W) \] and the corresponding generalized algebraic Riccati equations \[ -A^* W- WA- Q+ WSW= \Pi(W) \] are studied. Here \(A,Q= Q^*\), \(S= S^*\) are \(n\times n\) complex matrices, and \(\Pi(W)\) in a monotone linear function of the variable Hermitian matrix \(W ...

APPROXIMATE SOLUTION TO FRACTIONAL RICCATI DIFFERENTIAL EQUATIONS

Fractals, 2019
In this paper, quadratic Riccati differential equation of fractional order has been solved by employing the optimal homotopy asymptotic method (Optimal HAM) with application to random processes, optimal control and diffusion problems. Optimal HAM uses simple computations with quite acceptable approximate solutions which have close agreement with exact
