Based on the study of advantages of cascade control system and comparison PID （pmportional-ingegral-differential controller） HSIC （with human simulation intelligent control） algorithm, the main control strategy applied cascade-three parameters control approach based on HSIC for water level adjust in the boiler drum was presented. The control difficulty points of drum water level, three parameters system structure of boiler water level system, control strategy choosing and control algorithm of HSIC were studied. The simulation result points out that the system control quality is better by HSIC than by PID in main adjuster for the dynamic and steady performance. In addition, the basic system test shows that the control based on HSIC has better application values in practical engineering for main adjuster in the water level control of cascade-three parameters boiler drum system.
