A partial eigenstructure assignment problem with incomplete measured modal data is considered and the problem of its solvability is discussed. Besides, we propose a method to solve the problem such that unsuitable eigenvalues are replaced by the required ones while the remaining eigenstructure stays unchanged. The method is easily implementable and does not use QR factorization and singular-value decomposition. We also apply this method in flight control systems and numerical examples show the efficiency of our method.
