In this paper, a sliding mode tracking control methodology, based on the block control principle, for an arbitrary reference signal of multivariable systems with unstable zero dynamics is developed. The proposed approach does not require an exosystem and is applicable to any relative degree systems. It is shown that the two step design procedure of the sliding mode theory is applicable to provide tracking without an error. Nonlinear systems reducable to a regular form can also be incorporated in this approach. As an illustrative example, tracking controller for EGR/VGT diesel engine was designed which is a 7th order 2-input 2-output nonminimum phase system.
