%X A new analytical design method of decoupling controller matrix is proposed in terms of the standard internal model control structure for two-input two-output processes with time delays that are often encountered in chemical and industrial practice.Its advantage is that absolute decoupling for the nominal responses of system outputs can be implemented,and moreover,the controller parameters can be tuned on-line in a monotonous manner to cope with the plant unmodelled dynamics,so that significant decoupling regulation can be achieved.At the same time,for the process additive and multiplicative uncertainties mostly encountered in practice,the sufficient and necessary conditions for holding the control system robust stability are analyzed,and thus,an intuitive determination method is provided based on the spectral radius criterion.Finally,simulation examples are included to demonstrate the superiority of the proposed method over other recent approaches.
