英文摘要	Based on the non-uniqueness of control force matrix for structural active control pole assignment, an optimal pole assignment algorithm was proposed. The main difference between the performances of the algorithm and the classical LQR optimal active control was that structural active control weighted matries Q and R did not affect the proposed algorithm, so the new algorithm had obvious physical or engineering significance. Firstly, compared to the relationships among mathematical models of structural active control systems, based on the uniqueness of the transfer function matrix, the optimal zero-pole assignment was achieved in a complex plane. Secondly, the target transfer function matrix used to calculate its minimum state equation was established based on the expectative zero-pole, then the optimal pole assignment for structural active control was achieved. Finally, this algorithm's effectiveness and practicability were proved through an example.
