| 英文摘要 | This brief note deals with the synthesis of reduced-order H2 dynamic output feedback controllers for single-input-single-output linear systems. In particular, magnitude constraint on the controller coefficients, which is of practical interest but has been ignored in the literature, is also taken into account during the design. Sufficient linear matrix inequality (LMI) conditions for the existence of such controllers of arbitrary orders are derived in a unified manner and explicit formulas for computing the controllers are given. In comparison with several existing techniques in the literature, the advantages of our new approach are three-folds: (i) practical issue like the magnitude constraint on the controller coefficients is taken into account in the design, (ii) numerically reliable computation for the proposed LMI method is available, and (iii) the technique can be easily extended to the design of reduced-order controllers with other performances which admit LMI representations, e.g., H∞ performance, passivity property, generalized H2 performance. A numerical example is provided to demonstrate the potential of the proposed method. |
