本文所提方法的优越性.(The decoupling Smith control method is presented for multi-input-multi-output system with time-delays
which are often encountered in practical engineering. A new method for designing the decoupler based on the adjoint
matrix of the multivariable system model with time-delays is proposed. By analyzing the amplitude-frequency and phasefrequency
characteristics of the decoupled model, the decoupled model is reduced to a first-order model with time-delay.
According to the closed-loop characteristic equation of Smith predictor structure, a PI controller is developed by using the
principle of pole assignment for Butterworth filter. Sufficient and necessary conditions for robust stability are derived for
adaptive and multiplicative uncertainties commonly occurred in practice. Simulation results show the superiority of the
proposed method.)

奇异谱分析是近年来兴起的一种研究非线性时间序列数据的强大的方法。它根据所观测到的时间序列构造出轨迹矩阵，并对轨迹矩阵进行分解、重构，从而提取出代表原时间序列不同成分的信号，如长期趋势信号、周期信号、噪声信号等，从而对时间序列的结构进行分析，并可进一步预测。(Singular spectrum analysis is a powerful method to study nonlinear time series data in recent years. According to the time sequence structure of the observed path matrix, and the trajectory matrix is decomposed and reconstructed, thus extracting the signal representative of the original time series of different components, such as the long term trend signal and periodic signal and noise signal, through analyzing the structure of the time series, and further predict.)
