In order to ensure the secu rity, sta b ilization and econom y o the bo iler in a process, the drum level shou ld be contro lled c lose to a desired va lue. A three- mi pulse PID contro l sy stem o drum leve l is bu ilt w ith M ATLA B, and traditional P ID controlle r, uzzy adapted P ID contro ller, P ID contro lle r based on generic a lgo rithm are then taken in u se. H ow ever, the param eter o trad itional P ID contro ller is tuned by hum an, w h ich can t be changed any mo re, so the control e ect shou ld be urther mi proved. The uzzy adapted P ID contro l can tune the param eter on line, and P ID contro l based on g eneric a lgo rithm can search o r the best param eter autom atically, w hich are in comm on use in the drum leve l con tro l system. Compared w ith the smi u lation resu lt, it is show ed that us ing advanced P ID contro l can e ective ly qu icken the response, reduce the overshooting, decrease the r ise- tmi e, and mi prove the ab ility o overcom ing disturbance.
