Periodic output feedback stabilization of neutral systems. (English) Zbl 0849.93055
For the general class of neutral delay systems, the authors investigate when a system from this class is stabilizable by a feedback of the form \(u(n\tau + t) = K(t) y(n \tau)\), \(t \in [0,\tau)\). Here, \(u\) denotes the input, \(y\) denotes the output, and \(\tau\) is the sample time. Assuming that the open loop system has only finitely many unstable poles, which are controllable and observable, the authors prove the existence of such a feedback. An algorithm for constructing this feedback is given as well.
