摘　　要：介绍了麦克风效应和洛伦兹力作用对C-ADS注入器I的Spoke012超导腔的影响以及腔的压电陶瓷快调谐传递函数的特性,并详细叙述了依据传递函数特性搭建频率控制基本环路及利用阻尼技术来对腔的特定频率边带进行抑制的方法。所设计的PI控制基本环路和特定频率边带抑制环路在实际运行中得到使用,前者有效抑制了低频振荡,后者抑制特定频率振荡幅度达到15 d B。This paper introduces the influence of the Spoke012 superconducting cavities mounted in China Ac- celerator Driven sub - critical System （ C - ADS） caused by micro - phonies and Lorentz force detuning and the characteristics of the piezo fast tuner for 7# cavity in CM1. The design of the basic frequency - tuning loop and the side - band suppression loop by using the piezo characteristics and the damping technology is also described in details. Both the loops have been used in the commissioning. The former suppresses the low -frequency os- cillation effectively and file latter reduces the amplitude of the certain vibration by 15 dB.
