Small-Gain-Based Boundary Feedback Design for Global Exponential Stabilization of One-Dimensional Semilinear Parabolic PDEs

Abstract: This paper presents a novel methodology for the design of boundary feedback stabilizers for 1-D, semilinear, parabolic PDEs. The methodology is based on the use of small-gain arguments and can be applied to parabolic PDEs with nonlinearities that satisfy a linear growth condition. The nonlinearities may contain nonlocal terms. Two different types of boundary feedback stabilizers are constructed: a linear static boundary feedback and a nonlinear dynamic boundary feedback. It is also shown that there are fundame… Show more

“…Consider the Volterra operator 22 : (0,1) (0,1) , the time derivative of the control action would not be differentiable if the feedback law is nonlinear. That would not allow the homogenization of the boundary conditions (as performed in the proof of Theorem 3.1), which is necessary for the development of existence/uniqueness results.…”

“…In many cases the stabilization results are local, guaranteeing exponential stability in specific spatial norms. The papers [10,11] presented methodologies for global feedback stabilization of boundary controlled nonlinear parabolic PDEs: a small-gain methodology is applied in [10], while a CLF methodology is used for PDEs with at most one unstable mode in [11].…”
