Before discussing the stability test let us first introduce the following notions of stability for a linear time invariant (LTI) system… use z-transform, E(s) has infinite number of poles zeros in, E(z) has a 1 zero at z0 and 2 poles at ? dc gain? The c2d command requires three arguments: a system model, the sampling time (Ts) and the type of hold circuit.In this example we will assume a zero-order hold (zoh) circuit. Under periodic sampling, the sampled-data system is time-varying but also periodic, and thus it may be modeled by a simplifi ed discrete-time system obtained by discretizing the plant.
