Positive Sampled-Data Disturbance Attenuation: Separate Design

초록

Robust positive sampled-data observer-based output-feedback energy-to-peak disturbance attenuation is challenging problem because of the following reasons. (i) The typical Luenberger observer has a limited structure for guaranteeing closed-loop positivity. (ii) The conventional sampled-data control framework has no lever to manage closed-loop positivity during sampling intervals and at sampling instants. (iii) A separation principle is to be established for this problem. In this paper, we propose an affirmative methodology to solve this problem.
