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(nτ+t)=K(t)y(nτ), t[0,τ). Here, u denotes the input, y denotes the output, and τ 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.
