摘　　要：作动器系统作为直升机结构响应主动控制系统(active control of structure response, ACSR)执行元件的重要核心部件,其控制性能直接关系到振动的抑制效果。研制了一套基于永磁无刷直流电机驱动的离心式作动器原理样机,详细阐述了系统组成及工作原理,论述了作动器输出力频率、幅值和相位的调节方式,建立了偏心块的输出力方程,选取了MAXON公司生产的EC60 flat 411 678无刷电机作为驱动源。设计了作动器伺服控制系统,针对功率驱动中的隔离直流电源、自举二极管、自举电容、电流驱动能力及母线支撑电容等关键参数进行了详细设计。通过实验验证,电机转速误差最终被控制为1%以内,位置响应时间小于50 ms,振动抑制在0.001 5g(g为重力加速度)以下,取得了较好的控制性能,为离心式作动器系统在直升机平台的应用奠定了基础。As an important core component of the active control system of helicopter structure response(ACSR),the control performance of the centrifugal actuator system is directly related to the suppression effect.A prototype of a centrifugal actuator driven by a permanent magnet brushless DC(direct current)motor was developed.The system composition and working principle were described in detail,and the adjustment methods of the output force frequency,amplitude and phase of the actuator are discussed.The output force of the eccentric block was established.The EC60 flat 411678 produced by MAXON was used as the motor drive source.The actuator servo control system was designed,and the key parameters such as isolation DC,bootstrap diode,bootstrap capacitor,current drive capability and bus support capacitance in power drive were designed in detail.The experiments were carried out,the motor speed error is controlled within 1%,the position response time is less than 50 ms,and the vibration is suppressed below 0.0015 g(g is acceleration of gravity).The developed system has achieved good control performance,which lays a foundation for the application of centrifugal actuator system in the helicopter platform.
