At present industrial automation industries to measure the level of modernization has become an important sign of the level. PID control and smart or Controller PID controller (meters) now many products have been in the works in practice a wide range of applications, a wide variety of products PID controller. The major companies have developed a self-tuning PID parameters of the function of the smart regulator (intelligent regulator), which PID controller automatically adjust the parameters through intelligent self-tuning or adjustment, adaptive algorithms to achieve. PID control is used to achieve the pressure, temperature, flow, level controllers, to achieve PID control function of programmable logic controller (PLC), there can be realized PID control of the PC systems and so on.
This article from the following aspects of the PID study, with a focus on digital PID algorithms and simulation.
First of all, this brief introduction of the digital content related to the PID, as the figures behind the PID algorithm research and simulation provides a theoretical basis.
Then, this paper focuses on PID control experts and fuzzy PID control carried out in-depth Research.
Finally, the actual conduct of the simulation.
