Abstract

Based on analysing the proportional integral and differential(PID)algorithm and the dynamic matrix control(DMC)algorithm

the improved DMC algorithm based on PID performance idices(i.e.PIDDMC algorithm)has been deduced

the parameter selection and factors affecting control performance of the PIDDMC controller have been analysed in the time domain

giving out the range of parameter selection.Through emulation in cascade control system for superheated steam temperature in thermal power plant

and comparison with basic DMC algorihm

results show that the PIDDMC algorthm boasts more better comtrol performance.
