Late is Early [About This Issue]

Is doing nothing a viable control strategy? That question came to mind as I was reading the feature article of this issue of IEEE Control Systems Magazine (CSM) by Rifat Sipahi, Silviu-Iulian Niculescu, Chaouki Abdallah, Wim Michiels, and Keqin Gu. They write: This stability-seeking approach is known as the wait-and-act control strategy. The presence of properly timed multiple delays designed for waiting before executing a decision is an effective stabilizing control strategy.
