Application research of intelligent PID control based on the OPC
The intelligent PID control makes the practical furnace temperature curve well meet with standard ISO834.
To resolve the PID control problem of unknown systems, intelligent PID controller of zero-pole placement was designed according to PID control system theory and zero-pole placement theory.
For pouring furnace iron level control system, this thesis presents intelligent PID control algorithm according to the non-equilibrium characteristic of object.
