We investigate two complementary approaches to delayed feedback control: Noninvasive control
and global control. On the one hand, we study noninvasive control as inspired by Pyragas,
but going far beyond the scope of his original control scheme. In particular, we will address
control schemes which include symmetries of the system and new state-dependent control
schemes. On the other hand, we introduce the ambitious new concept of global control,
which targets the global nonlinear dynamics, rather than just local linear in-/stability. Both
settings aim at novel and broadly applicable principles of delayed feedback control.
