摘要： 研究基于声辐射模态理论进行有源控制解耦中压电作动器的位置优化问题。以往的研究得出：只要四组作动器满足某种对称形式布置，就可以实现声辐射模态的有源控制解耦，但是满足对称性布置的四组作动器位置有无数个。在主动控制中，压电作动器的位置如何布置一直是个难题。论文以输入控制功率最小化为目标，对四组压电作动器的位置进行了优化。

Abstract: The location of optimization of piezoelectric actuator based on the theory of radiation modes in the active control decoupling is studied. Previous researches have proposed that as long as four groups of actuators are arranged symmetrically, active control decoupling based on radiation modes can be achieved. Since there are many symmetrical layouts for the four groups of actuators, it is worth studying which layout is the best. In this paper, based on the object of minimizing the input control power, the locations of the four groups of piezoelectric actuators are optimized.
