System identi®cation methods build mathematical models of dynamical systems based on observed data. The intended use of the model should always be re¯ected in the methods and techniques used for identi®cation. In this paper an identi®cation scheme is derived for the case where the model is going to be used for GMC controller design. The aim of GMC control is to make the output approach a setpoint along a given desired trajectory. This is re¯ected in the identi®cation scheme which is non-standard in two ways. Firstly, the emphasis is on the output trajectories of the models, and secondly we try to make the prediction errors follow an error trajectory determined by the controller parameters. Simulation studies are included which show that the derived identi®cation scheme performs well.
