Abstract : "In this article, an output feedback control scheme is proposed for trajectory tracking of differentially
flat systems. After applying the exact feedforward linearization, the tracking error dynamics is linearized as a
linear time-varying (LTV) system, where only the state matrix is time-varying while the input and output matrices
are time-invariant. Using linear parameter-varying (LPV) techniques based on polytopes, for the LTV system the
controller matrices, which are set to be affine on time-varying parameters, are calculated by solving a set of linear
matrix inequalities (LMIs). An example for trajectory tracking of a two-wheeled mobile robot is given to show the
effectiveness of the proposed method."
