Abstract:
In order to improve the control performances of the large inertia with large time delay process and the unstable process,the two degree of freedom model driven PID control system are introduced.The actual controlled process can be changed into a first-order model with dead time by PD feedback compensator of the system.The time constant of the first-order model is much smaller than that in actual controlled process.Its structure design principle and the parameter tuning method are analyzed.It is applied to the main steam pressure controlled process with large inertia and large time delay of the circulating fluidized bed boiler.The research results show that the two degree of freedom model driven PID control system has better control performance than the conventional PID control system and the fuzzy auto tuning PID control system.It has the advantages of simple structure,good real-time performance,and its design and implementation are very convenient in the DCS system.So it is easy to be popularized and applied.
