Partial Approximate Controllability for Linear Stochastic Control Systems

SIAM Journal on Control and Optimization, 2019
Summary: This paper is devoted to studying controllability problems of linear stochastic control systems with controls only in the drift terms. It is well-known that such a system is not exactly controllable. We first construct an example to show that it is also not approximately controllable under some natural condition.

Duality and approximate controls

Journal of the Franklin Institute, 1968
Abstract The computation of approximate controls for the terminal problem for linear systems is considered. These controls can be made to steer the terminal state vector arbitrarily close to the desired terminal position; their norms will generally be smaller than the norm of the exact optimal control which achieves the desired terminal state. It is

Uniform Approximation of Infinite Horizon Control Problems for Nonlinear Systems and Stability of the Approximating Controls

IEEE Transactions on Automatic Control, 2009
This technical note addresses the approximation of the infinite horizon problem and the stability of the approximating controls generated by the receding horizon method. The setup takes into account systems and costs that may be nonlinear and discontinuous, with possibly state and control constraints, allowing for a wide range of problems.

Robust approximation and control

IEEE Control Systems, 1997
An algorithmic procedure has been implemented. Its input data are the frequency samples of a MIMO high order (possibly infinite dimensional) model and its output is a controller for that system. The procedure considers the approximation error as additive uncertainty and designs for robust performance of a mixed sensitivity problem by using H/sup /spl ...

Approximate time-optimal control via approximate alternating simulations

Proceedings of the 2010 American Control Conference, 2010
Symbolic models of control systems have recently been used to synthesize controllers enforcing specifications given by temporal logics, regular languages, or automata. These specification mechanisms can be regarded as qualitative since they divide the set of trajectories into bad trajectories (those that should be eliminated by control) and good ...

Remarks on approximate controllability

Journal d'Analyse Mathématique, 1992
The problem of exact and approximate controllability for the wave equation with boundary control is studied. It is introduced the duality method which allows the treatment of the original problem via variational inequalities. Many pertinent remarks are made and some open problems are formulated.

Controllability of an approximately defined control system

Sbornik: Mathematics
We introduce the notion of controllability of a system of ordinary differential equations with respect to a prescribed function and present conditions that guarantee the controllability (with respect to this function) of both the original control system and all control systems close to it. Bibliography: 10 titles.
