Aiming at the characteristics of mini-type testing reactor, this paper introduces some techniques that used to control the temperature of this kind of reactors, such as autotuning for PID controllers, cascade control, sampling adjustment, program adaptive control and programed temperature control.

By the software,the system was tested and the parameters of the PID algorithm were set up by PID autotuning VI.

The autotuning PID/ PI based on the improved relay feedback identification is proposed and it is applied in the typical long time lag and large inertia ob- ject— the moisture and basis weight control system of paper machine, and it has been proved that the control effect is satisfactory.

Process Identification and PID Parameters Auto-tuning Theory and Application in HVAC System;

A PID auto-tuning method based robust specification for integrating processes with time delay was proposed using two feedback loop design technique.

An auto-tuning controller,based on the modified relay feedback identification,was designed with respect to the phase margin.

The common use control systems and effective algorithms are discussed,in which soft-sensor technique and self-tuning PID are emphasized.

The system used a late startup and self-tuning PID temperature control strategies,realized the extruder preheating stage all arrived the design temperature value at the same time,and the accuracy of temperature control was higher than the existing machines on the majority of single-point-temperature control.
