Noncommutative optimal control and quantum networks [PDF]

, 2006
Optimal control is formulated based on a noncommutative calculus of operator derivatives. The use of optimal control methods in the design of quantum systems relies on the differentiation of an operator-valued function with respect to the relevant ...

Optimizing walking controllers [PDF]

ACM Transactions on Graphics, 2009
This paper describes a method for optimizing the parameters of a physics-based controller for full-body, 3D walking. A modified version of the SIMBICON controller [Yin et al. 2007] is optimized for characters of varying body shape, walking speed and step length. The objective function includes terms for power minimization, angular momentum minimization,

Radial Symmetry and Monotonicity of Solutions to a System Involving Fractional p-Laplacian in a Ball

Advances in Mathematical Physics, 2018
In this paper, we study a nonlinear system involving the fractional p-Laplacian in a unit ball and establish the radial symmetry and monotonicity of its positive solutions. By using the direct method of moving planes, we prove the following result.

Optimal Opinion Control: The Campaign Problem [PDF]

, 2014
Opinion dynamics is nowadays a very common field of research. In this article we formulate and then study a novel, namely strategic perspective on such dynamics: There are the usual normal agents that update their opinions, for instance according the ...

Locally optimal controllers and globally inverse optimal controllers [PDF]

Automatica, 2014
In this paper we consider the problem of global asymptotic stabilization with prescribed local behavior. We show that this problem can be formulated in terms of control Lyapunov functions. Moreover, we show that if the local control law has been synthesized employing a LQ approach, then the associated Lyapunov function can be seen as the value function
