Generalized minimum variance control is designed in a multi‐rate system where the sampling interval of a plant output is longer than the holding interval of a control input. Because new design parameters are introduced, intersample ripples in the multi‐rate system are suppressed by weighting the variation in the control input. Furthermore, the proposed method is an extension of a conventional design method. Finally, simulation results are illustrated in order to show the effectiveness of the proposed method. © 2006 Institute of Electrical Engineers of Japan. Published by John Wiley & Sons, Inc.
