Examples
- The sprt was used to test error residual matrix between estimated matrix and measured matrix . based on the test result , it need to validate single parameter if necessary . finally , the on - line run status of the system and its parameters that whether natural or not are judged through these processes
通过锅炉专家制定的试验设计方案得到了有效的实验数据,利用最值模型以及向量排序模型筛选出记忆矩阵,然后通过记忆矩阵对观测矩阵进行实时训练得到预测矩阵,再利用sprt方法对预测矩阵与观测矩阵的残差矩阵进行检验,对检验结果判断,如有必要需对单参数进行验证,最终通过这个过程判断出系统及各个参数在线运行的稳定性。 - Based on the assumption of periodic rubbing force in rotor system , the rubbing forces onto each node of rotor system are estimated by modal expansion technique and the sub - harmonic decomposition of residual matrix between faulty and faulty - free vibration signals of rotor system through fft ( fast fourier transformation )
基于转子系统碰摩力的周期性假设，利用模态扩展方法，对故障和健康转子系统振动信号的残差矩阵进行傅立叶级数的分频谐波近似，估算得到转子轴承各节点的碰摩力。 - The main part of this hybrid algorithm is a chebyshev iteration which applies chebyshev polynomials to act on initial vectors and makes the obtained vectors close to the wanted eigenvectors ; the second one is the preconditioning subspace iteration method which uses a preconditioning matrix to impact the residual matrix obtained from the iteration procedure , so the distribution of eigenvalues is improved
第一个改进算法是用chebyshev多项式加速的子空间迭代法，它是用chebyshev多项式作用初始向量，使其更接近所要求的特征向量。第二个改进算法是对每次迭代所得的残余矩阵直接进行预处理以改善矩阵特征值的分布。
