| Description |
The purpose of the work is to develop a simple temperature regulator of stand thermostat for thermocouples research, which will reduce the time of temperature establishment. Tubular ceramic resistor was used as a working element. First the PID-regulator of thermostat temperature was implemented and studied. For the setup of the PID-regulator on the basis of the experimentally removed acceleration curve with input action in the form of leap, as a result of solving the identification problem, the thermostat dynamic model was obtained. This model was investigated in the interactive program for modeling, imitation and analysis of dynamic MATLAB&SIMULINK systems for the purpose of regulator’s speed optimization with a given temperature tolerance. As a result we found the speed limit of the classical thermostat PID-regulator. The combined P-PID-regulator of temperature and the algorithm of its work were developed to increase thermostat speed. The Pregulator is used for forced heating at thermostat start. Then the main PID-regulator providing a zero error of regulation and effective temperature stabilization at a set level turns on. A corresponding transition criterion was developed to find the moment of transition from P- to PIDregulator. The suggested technique of the regulator setup provides the adaptability of its parameters to the difference between setting and room temperature. Natural tests showed that the developed work algorithm, transition criterion and combined P-PID-regulator’s setup technique provide an increase in thermostat speed by 2,3 times in comparison with the classical PID-regulator. In this case the time of temperature establishment in the thermostat does not exceed 1,5 minutes at the set tolerance 0,2 0C. Предложены алгоритм работы и методика настройки комбинированного регулятора тем- пературы термостата, обеспечивающего существенное сокращение времени установления температуры в сравнении с классическим ПИД-регулятором. |
