Engineering cybernetics is not just about control, but more so about the interplay between information and control. Our understanding of the basic concepts such as feedback and disturbance deepens with a critical reflection on how critical information is recognized and obtained in the context of control design, so does our understanding of the past inventions and design principles. Prof. Jingqing Han, a pioneer, initiated the debate with an article in this journal 27 years ago. Sharing deep concerns regarding the premise on the accurate mathematical model in control theory with Prof. H.S. Tsien, who raised the problem of disturbance and uncertainties in control, Prof. Han made the crucial leap from the model-based design to the information-based design. The ensuing dualistic paradigm of controller-rejector design, with active disturbance rejection control as but one embodiment, provides both a framework and a new technological basis for the renewal and standardization of general purpose industrial control technologies, as well as a path back to the original vision of engineering cybernetics from Prof. Tsien. From the south-pointing chariot\\ to engineering cybernetics, from PID to active disturbance rejection control, from humanity to science and technology, from east to west, an information-centric conceptualization of control has persisted over centuries and is coming to fruition.
