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.)
