APPROXIMATE SOLUTIONS TO A WEIGHTED MIXED-SENSITIVITY H-INFINITY-CONTROL DESIGN FOR IRRATIONAL TRANSFER MATRICES

摘要

Approximate solutions to a weighted mixed-sensitivity H-infinity-control problem for an irrational transfer matrix are obtained by solving the same problem for a reduced-order (rational) transfer matrix. Upper and lower bounds are given in terms of the solution to the reduced-order problem and the approximation error. A delay example and a pde example are discussed. [References: 22]
