| 摘 要： | 提出了有源结构声控制（ＡＳＡＣ）的单通道多作动器控制新策略。把常规的单通道输入输出（ＳＩＳＯ）系统中的作动器作为主作动器，设置多个从作动器，优化控制力，从面形成了单通道控制多个作动器的新策略。使多个作动器形成和初级激励相适应的模态分布，有效地抑制结构的振动和噪声。仿真试验表明，该策略比常规的ＳＩＳＯ的降噪量平均提高１５￣２０ｄＢ。

| Abstract: | A new singlechannel mulitiactuator tactics for Active Structural Acoustic Control (ASAC). In this new tactics, the actuator which is used in ordinary SISO controller is chosen as master actuator, and an array of actuators as slave actuators, and the optimization of control forces is integrated. The mechanism of this tactics is to produce the similar modal distribution with the primary disturbances and then effectively suppress vibration and sound radiation .Numerical experiment shows that the sound power reduction of this tactics is 15-20 dB higher than that of SISO controller. |
