As to the polyreference implemention of the least - squares complex frequency - domain estimator in mathematical separation technique of modes, this thesis builds a right matrix - fraction description model to estimate the system poles. then frequency point stabilization diagram is set up and analyzed to automatically determine natural frequencies, modal damping ratios and modal participation factors. finally mode shapes are identified based on the least squares theory
對于模態數學分離技術的多參考點最小二乘復頻域識別技術，先建立右矩陣分式頻響模型，識別出系統極點，再通過建立和分析頻率點穩態圖，能自動的確定出結構的固有頻率、模態阻尼比和模態參與因子，最後根據最小二乘原理識別出模態振型向量。 -
In contrast to phase separation ( curve - fitting ) approaches which are largely mathematical, phase resonance testing is a physical technique. when a structure is vibrating in a normal mode, the undamped natural frequency and normal - mode shap of the structure are directly measured. in the classic phase resonance testing, the test data processing is simpler and the results are more accuracy
相對于相位分離法來說，相位共振法是一種比較直觀的物理識別方法，在結構做「純模態」振動時，通過物理測量直接獲得模態參數;試驗數據處理工作量小，且精度一般比單輸入系統高。
