In this paper,adopting OPC server ,OPCActiveX control taking place IO driver program, implement data communion and in- terlinkage with Matlab and increase the functions of the huge sign,numericcal value compute,matrix operation and figure display with no disturbance and implement advance control and optimize control.
If we want to control multivariable system, especially carrying out some advance control algorithms such as internal model control and predictive control that are based on model, system model is prerequisite.
In this paper the advance control arithmetic of subsection self-adopt control and so on implemeted by using Matlab application connect with controler of the SHCAN200 fieldbus series instrument directly ,update the parameter of controler in real time and implement subsection self-adopt control.
At the same time, the difficulties and solution of advance control, quality control, and information management for expressway ITS project will be found out.
This article deals with an example of advance control techniques applied to a biochemical system, the mathematical model and the constrains derived from the discrete implementation of a continuous control policy.
