Approximate Dynamic Programming via Sum of Squares Programming [PDF]
, 2012 We describe an approximate dynamic programming method for stochastic control problems on infinite state and input spaces. The optimal value function is approximated by a linear combination of basis functions with coefficients as decision variables.

Comparison of Perron and Floquet eigenvalues in age structured cell division cycle models [PDF]
, 2008 We study the growth rate of a cell population that follows an age-structured PDE with time-periodic coefficients. Our motivation comes from the comparison between experimental tumor growth curves in mice endowed with intact or disrupted circadian clocks,

Basic Control Theory for Linear Fractional Differential Equations With Constant Coefficients
Frontiers in Physics, 2020 In this paper we present an analogous result of the famous Kalman controllability criterion for first order linear ordinary differential equations with constant coefficients that applies to the case of linear differential equations of fractional order ...

Gaussian process model based predictive control [PDF]
, 2003 Gaussian process models provide a probabilistic non-parametric modelling approach for black-box identification of non-linear dynamic systems. The Gaussian processes can highlight areas of the input space where prediction quality is poor, due to the lack ...

Mittag-Leffler stabilization of fractional-order nonlinear systems with unknown control coefficients
Advances in Difference Equations, 2018 In this paper, we consider the problem of Mittag-Leffler stabilization of fractional-order nonlinear systems with unknown control coefficients. With the help of backstepping design method, the stabilizing functions and tuning functions are constructed ...

Two Inverse Problems Solution by Feedback Tracking Control
Axioms, 2021 Two inverse ill-posed problems are considered. The first problem is an input restoration of a linear system. The second one is a restoration of time-dependent coefficients of a linear ordinary differential equation.

Optimal Control Systems by Time-Dependent Coefficients Using CAS Wavelets
Journal of Applied Mathematics, 2009 This paper considers the problem of controlling the solution of an initial boundary-value problem for a wave equation with time-dependent sound speed. The control problem is to determine the optimal sound speed function which damps the vibration of the ...
