Development of a simulation platform for PID autotuning

Abstract

An autotuning simulation platform consisting of a program built by C for the

autotuning of PID controller which keeps the PID controllers in closed loop is develop

in this paper. First, a virtual process was established using Matlab, which should be

stably controlled in closed loop. Then a database was built using Microsoft SQL server,

through which the data of virtual process exchange with the data of PID autotuning

program. Finally, a PID autotuning program was designed, which can tune the

parameters of the PID controllers according to the state of the virtual process.
