Taking once through boiler in a supercritical 765 MW unit as the object
a pole-placement adaptive control algorithm for output and enthalpy of the unit was studied
based on the DCS platform of HOLLIAS-Con Maker control system of Beijing HollySys System Engineering Co.Ltd.According to the dynamic model of the 765 MW unit and the characteristics(slow time varying and nonlinearity) of the once through boiler
the pole-placement adaptive PID control scheme was designed.Besides
the modeling
real-time simulation
data processing and link of this algorithm were conducted on the DCS platform mentioned above.Results show that
the pole-placement adaptive PID control system has good tracking and adaptive ability
and its control quality is higher than that of the traditional control systems.
