The example is interactive and shows the effect of changing transfer function coefficients on system stability. The attached file is a VI created using the LabVIEW Control Design Toolkit for stability analysis of a second order linear system. The system is represented by a transfer function and the user can change the coefficients interactively on the front panel of the VI (Figure 1) to examine changes in the pole values, pole-zero map, stability indicator, and step response. The block diagram of the VI is shown in Figure 2. This VI can be used as an in-class demonstration or homework problem to teach students about stability concepts and can be easily modified to describe higher order transfer functions or MIMO systems described with a state space representation.
