Implementing Dynamic Matrix Control for Water Tank System based on FF Field-bus

To overcome the difficulty of implementing DMC algorithm in monitoring software of FF fieldbus system, the strategy of using Matlab7.0 OPC tool package to realize communication with OPC server and DMC control is proposed. The merits of the matrix language, i. e. , simple, terse, and high effective, are fully elaborated. Comparing with PID algorithm, dynamic matrix control algorithm is an effective optimal predictive control algorithm, it is well accurate and robust to the system with dead time characteristic. The result of simulation shows that by adopting this strategy, the development period of the monitoring program can be shortened, and the expected control effects can be reached.
