| 英文摘要 |
| In this paper, the existence of unified H∞ dynamic observer proposed by article [24] is studied. and whether
there is a solution for a special set of Sylvester matrix equations which is needed by the existence of unified H1 dynamic
observer is discussed. By using the matrix theory, this paper conducts relevant derivation and demonstration, and finally
finds out the necessary and sufficient conditions for the Sylvester matrix equations to have solutions, as well as the structure
of solutions. It shortens the search range of parameters in the UHDO (unified H∞ dynamic observer) design problem.
And gives the algorithm for solving the Sylvester matrix equations. Finally, different values of arbitrary parameters in the
solution structure in the simulation case show the influence on the unified H∞ dynamic observer. |
