| 中文摘要 | 为解决陷波滤波器在实际应用中存在影响控制系统稳定性的问题和兼顾系统的干扰抑制和稳定特性,提出了一种陷波滤波器的设计方法。该陷波滤波器采用通用式结构,其中心频率分布在转子转速附近以抑制不平衡振动。陷波滤波器中的其他三个参数,与滤波器的带宽和极点分布相关,可影响系统的稳定性。推导出包含该陷波滤波器的系统传递函数和稳定方程,综合采用根轨迹、频域分析的方法,给出了这三个参数与系统稳定性的关系。然后考虑稳定裕量、刚度、振荡幅度和滤波效果的要求以设计陷波滤波器。试验结果表明,采用该设计方法的陷波滤波器,不仅使磁电轴承的转速衰减率和控制电压噪声分别减小91％和67％,而且也使系统的稳定性指标和附加振荡幅度满足设计指标。; If notch filter is inserted into magnetic and electrostatic suspension system to eliminate unbalance vibration, the stability of the system is influenced. A design method of the notch filter is put forward, which gives the consideration of the restraining of the disturbance and the stability of the system. The filter used a kind of general structure, whose central frequency located nearby the rotation speed to reduce the unbalance vibration. The other three parameters were relevant to the bandwidth and the polar distribution of the filter, which could be used to influence the stability of the system. The transfer function and the stability equation of the system with the notch filter are found, and the root locus and frequency domain method are used to find the mathematic relationship between filter parameters and system properties. Then the filter is designed, which takes margin, stiffness, amplitude and filtering effect into consideration as a whole. The experimental result shows that after using the notch filter, the speed attenuation and the voltage are reduced by 91% and 67% respectively, and the stability margin and the vibration amplitude meet the design target.; 国防基础与应用预研资助项目(9．4．4)。 |
