ASYMPTOTIC BEHAVIOR OF A SCHRODINGER EQUATION UNDER A CONSTRAINED BOUNDARY FEEDBACK

Design of controller subject to a constraint for a Schrodinger equation is considered based on the energy functional of the system. Thus, the resulting closed-loop system is nonlinear and its well-posedness is proven by the nonlinear monotone operator theory and a complex form of the nonlinear Lax-Milgram theorem. The asymptotic stability and exponential stability of the system are discussed with the LaSalle invariance principle and Riesz basis method, respectively. In the end, a numerical simulation illustrates the feasibility of the suggested feedback control law.
