概要 This study deals with the problem of aperiodic-disturbance rejection for a class of plants with non-linear statedependent uncertainty in a modified repetitive-control system (MRCS). Since both the non-linear uncertainty and the disturbances are often unknown, an equivalent-input-disturbance (EID) estimator is constructed using a full-order state observer with variant system matrix to estimate them. The EID estimate, which exhibits the overall effect on the output of the non-linear uncertainty and all types of disturbances, is incorporated into a linear repetitive control law to compensate for the non-linear uncertainty and the disturbances. A continuous-discrete two-dimensional model of the EID-based MRCS is built that enables the preferential adjustment of the control and learning actions. A sufficient condition for the robust stability for the EID-based MRCS is given in terms of a linear matrix inequality. It yields the parameters of the repetitive controller and the EID estimator. Finally, a numerical example demonstrates the design procedures and illustrates the effectiveness of the method.
