Abstract: In this papcr, the MLMO principle that more large and more complcx the controlled process is, more objcctivcs there are to be satisfied to control the process-with high quality is proposed. The concept and the approach of process partition are also proposed to model the complcx process with varying characterigtics. To multiobjcctivcly control the process with linguisitic uncertainty, the result-related fuzzy multiobjcctivc predictive control approach(FMPC) is put forward and finally the intelligent multiobjcctivc optimal control(IMOC) which includes the process partition method, FMPC and the expert system technique is prcscnted and applied to the control of the train-travelling process with good results.
