Sampled-Data Stabilization; A PBC Approach

Two sampled-data design procedures ensuring stabilization of passive systems are described in the general framework of passivity-based control (PBC) strategies. The first one makes reference to some modified output with respect to which passivity under sampling can be preserved. The second one can be interpreted as the sampled-data equivalent to the celebrated continuous-time stabilizing and damping L_g V-controller. A simulated example illustrates the performances.
