| With the research and development of controlling theory, a great number of entities have, on the basis of implication of DCS or some regular control (that is PID controller),continuously developed some advanced process control software, 90% of which are in the requisition of common implementation of PID loops. Those are powerful proof that PID algorithm is still the most basis and most being used one. Therefore, tuning of PID controller parameters is very important, and it is also the base for advanced control and optimized control.PID controller which is on the basis of internal model control, not only keeps the characteristics of original PID controller, but also has all the advantages of internal model control. With PID format, it can be easily adopted and understood by all the technicians, be implemented by DCS, the modern controlling hardware, and be used to reconstruct controlling system in existence.On the basis of IMC-PID software package developed by BUCT... |
