摘　　要：A method of measuring the interactions in a multivariable control sys-tem(MVCS)in time domain is defined in this paper.An intelligent decoupling com-pensator is designed in terms of the concept of fuzzy control,so that the auto-tuningof controllers’ parameters in a 2×2 MVCS can be turned into that of two independentsingle-loop control systems(SLCS).The method presented in the paper has success-fully been used in a simulation experiment on the automatic tuning of a coordinatedcontrol system(CCS)in the drum-boiler turbogenerating unit(DBTU)and the simu-lation results axe satisfactory.A method of measuring the interactions in a multivariable control sys- tem(MVCS)in time domain is defined in this paper.An intelligent decoupling com- pensator is designed in terms of the concept of fuzzy control,so that the auto-tuning of controllers' parameters in a 2×2 MVCS can be turned into that of two independent single-loop control systems(SLCS).The method presented in the paper has success- fully been used in a simulation experiment on the automatic tuning of a coordinated control system(CCS)in the drum-boiler turbogenerating unit(DBTU)and the simu- lation results axe satisfactory.
