Boundary Feedback Control of Complex Ginzburg-Landau Equation with A Simultaneously Space and Time Dependent Coefficient

Linearized complex Ginzburg-Landau equation models various physical phenomena and the stability controls of them are important. In this paper, we study the control of the LCGLE with a simultaneously space and time dependent coefficient by transforming it into a complex heat equation. It is shown that under certain conditions on the coefficient functions a2(x̃, t̃), the exponential stability of the system at any rate can be achieved by boundary control based on the state feedback. The kernels are explicitly calculated as series of approximation and shown to be twice differentiable by using the method of dominant. Both the exponential stabilities of the systems with Dirichlet and Neumann boundary conditions are strictly proven.
