Step Responses of Nonlinear Non-Minimum Phase Systems

• For nonlinear systems, instability of the zero dynamics is known to correspond to the non-minimum phase property of linear systems. For linear systems it is also known that non-minimum phase is associated with certain step response behavior e.g. the initial direction of the step response is opposite to the final value. The corresponding step response properties of nonlinear systems are investigated in this contribution. It is also investigated whether a certain nonlinear canonical form gives insight into the relation between step response and non-minimum phase behavior.
