Analysis and optimal boundary control of a nonstandard system of phase field equations [PDF]

open access: yes, 2012
We investigate a nonstandard phase field model of Cahn-Hilliard type. The model describes two-species phase segregation and consists of a system of two highly nonlinearly coupled PDEs.

Newton control laws for nonlinear controller design [PDF]

open access: yes, 1985
Strong similarities between control theory and the theory on the solution of operator equations have been observed and basic results in control theory have been derived from operator theory arguments.

Global stabilisation for a class of stochastic continuous non‐linear systems with time‐varying delay

open access: yesIET Control Theory & Applications, 2021
This paper studies the problem of global stabilisation for a class of continuous but non‐smooth stochastic non‐linear systems with time‐varying delays. Other than the traditional backstepping recursive control, a concise controller of the nominal system ...
