Design for Temperature Control System of Ignition Point Detection Instrument Base on Self-adaption

Abstract

For the purpose of better solving the problems about temperature control in ignition point detection, this paper studies the design for temperature control system of ignition point detection instrument based on self-adaption. This research is carried out through referring to related documents and least square algorithm to design hardware structure, temperature control system, technology and others of instrument. The result shows that the temperature response of controlled heating furnace can better track the given temperature rising curve and can reduce the effect produced by time delay and large inertia on temperature control system of ignition point detection instrument. The self-adaption Dahlin controller in this paper can better meet the requirements of heating rate control in ignition point test for coal sample and with fine practicality and accuracy, which is worthy of application.
