Reducing a MIMO Control System to a Form with a Relative Degree

摘要

Some methods of control theory are applicable to a control system only if the conditions of a relative degree is met. These conditions are not always met, but it is sometimes possible to reduce such systems to a form with a relative degree using output transformation. In this work, we propose an algorithm for computing such a transformation that can be applied to discrete-time linear systems with as many inputs as outputs.
