The zero dynamics plays an important role in the areas of modelling, analysis, and control of linear and non-linear systems. For the first two mentioned areas a motivation is given for the applicability of the zero dynamics and a few examples are presented where the zero dynamics is used. The zero dynamics gives additional insight in the structure of the model employed and is an aid in modifying a model to satisfy some needs of the modeller. For non-linear systems the analytical calculations to get the zero dynamics by paper and pencil may be quite involved. Symbolic computation has been used to overcome this difficulty. For a reasonable class of systems the computation can be performed without human aid or intervention, making the zero dynamics procedure a feasible and valuable addition to the toolbox of the modeller, analyst, or control system designer. The complexity of the problem and of the algorithms is too high to expect any results in reasonable space and time when a problem is more than moderately sized.
