Abstract:
We give an introduction to the control triple method, a new type of noninvasive spatio-temporal feedback control. The notion of a control triple defines how we transform the output signal, space, and time in the control term. This Ansatz, especially well suited for the control of partial differential equations, does not exist in the literature so far. It incorporates the spatio-temporal patterns of the equilibria and periodic orbits into the control term. We give linear examples to demonstrate the success of the control triple method.
