An approach via inertial-manifold theory is presented as a way to study the problem of stabilizing semilinear diffusion systems using finite-dimensional controllers. It is shown that a Sakawa type of controller plays an important role in the construction of an inertial manifold for the closed-loop (controlled) semilinear diffusion system. This means that the use of a Sakawa type of controller reduces the stabilization problem for the closed-loop system to the one on the inertial manifold.
