A tracking controller design with preview action for a class of nonlinear Lur'e systems with time-varying delays and external disturbances
In this paper, the tracking control problem for a class of discrete-time nonlinear Lur’e systems with time-varying delays and external disturbances is studied via a preview control method. First, a novel translation approach is introduced to construct the augmented error system for Lur’e systems. The output tracking problem is thereby transformed into a guaranteed cost controller design problem. To produce an integral control action that can eliminate the static error, a discrete integrator is...
