In order to simplify control parameters design , the modeling method of equivalent inductance is put forward and validated by simulation and experimentation 在此基础上为简化控制系统参数设计,利用等效电感建模法建立了调速系统在复频域内的动态数学模型,并进行了仿真和试验验证。
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 对于模态数学分离技术的多参考点最小二乘复频域识别技术,先建立右矩阵分式频响模型,识别出系统极点,再通过建立和分析频率点稳态图,能自动的确定出结构的固有频率、模态阻尼比和模态参与因子,最后根据最小二乘原理识别出模态振型向量。
