A cubic C0 interior penalty method for elliptic distributed optimal control problems with pointwise state and control constraints

open access: yesResults in Applied Mathematics, 2020
We design and analyze a cubic C0interior penalty method for linear–quadratic elliptic distributed optimal control problems with pointwise state and control constraints. Numerical results that corroborate the theoretical error estimates are also presented.

Maximum Principle for Forward-Backward Doubly Stochastic Control Systems and Applications [PDF]

open access: yes, 2010
The maximum principle for optimal control problems of fully coupled forward-backward doubly stochastic differential equations (FBDSDEs in short) in the global form is obtained, under the assumptions that the diffusion coefficients do not contain the ...

On the linear quadratic data-driven control [PDF]

open access: yes, 2007
The classical approach for solving control problems is model based: first a model representation is derived from given data of the plant and then a control law is synthesized using the model and the control specifications.

Robust servo linear quadratic regulator controller based on state compensation and velocity feedforward of the spherical robot: Theory and experimental verification

open access: yesInternational Journal of Advanced Robotic Systems, 2023
There are few studies on the lateral motion of spherical robots. In this article, a new algorithm is proposed to solve the problem of low control accuracy of the lateral motion.

Optimal Unravellings for Feedback Control in Linear Quantum Systems [PDF]

open access: yes, 2004
For quantum systems with linear dynamics in phase space much of classical feedback control theory applies. However, there are some questions that are sensible only for the quantum case, such as: given a fixed interaction between the system and the ...

Guaranteed robustness properties of multivariable, nonlinear, stochastic optimal regulators [PDF]

open access: yes, 1983
The robustness of optimal regulators for nonlinear, deterministic and stochastic, multi-input dynamical systems is studied under the assumption that all state variables can be measured.

Optimal Control for a Multistage Uncertain Random System

open access: yesIEEE Access, 2023
Chance theory is a mathematical methodology for modelling complex systems including both uncertainty and randomness. Based on chance theory, this paper introduces the optimal control model for a multistage uncertain random system.

Maximum Principle of Discrete Stochastic Control System Driven by Both Fractional Noise and White Noise

open access: yesDiscrete Dynamics in Nature and Society, 2020
In this paper, we investigate the necessary optimality conditions of the discrete stochastic optimal control problems driven by both fractional noise and white noise. Here, the admissible control region is not necessarily convex.
