“…As the control terms vanish on the target pattern (u p , v p ), this type of control is called non-invasive. For control of patterns in PDEs, a wide range of possible control terms can be applied, including spatio-temporal delay, proportional feedback, or combinations of these 12,13,21,22 In this paper, we investigate one specific form of non-invasive control, applied to the toy model (2). We leave the u-equation intact, and add proportional feedback control to the v-equation, yielding…”
