“…As the time-discretization of control systems, periodic sampling and control-updating are widely used. Various problems on periodic sampleddata control have been studied for infinite-dimensional systems; for example, stabilization [14,15,21,22,24,29,34,38], robustness analysis of continuous-time stabilization with respect to periodic sampling [23,30,31], and output regulation [17][18][19]25,37]. Event/self-triggering mechanisms are other time-discretization methods, which send measurements and update control inputs when they are needed.…”
