Abstract

The invention provides a temperature control method and system. The system comprises a temperature sensor, a neural network controller and a temperature adjusting device. The temperature sensor is used for obtaining a current temperature value of the environment; the neural network controller is used for substituting the current temperature value of the environment and a target temperature value into a preset temperature model to generate a temperature control signal; and the temperature adjusting device is used for adjusting the current temperature value of the environment according to the temperature control signal to enable the current temperature value of the environment to be equal to the target temperature value. The environment temperature is controlled through the neural network controller capable of carrying out self learning, so that control precision of the temperature control system can be improved, adjusting time is reduced, and stability precision is improved; and throughthe self learning method, the temperature control system can carry out self learning on temperature variation rules of different environments, so that manual intervention is not necessarily need, anduniversality is improved.

Description

technical field [0001] The invention relates to the field of temperature control, in particular to a temperature control method and system. Background technique [0002] Temperature is a common control variable in industrial production and life. With the continuous development and progress of technology, the requirements for heating and cooling performance are also increasing, and the requirements for temperature control accuracy are also getting higher and higher. [0003] The traditional temperature control adopts the PID control method. The PID control method is mainly based on the proportion, integral and differential of the deviation between the temperature given value and the actual temperature value, and forms the control amount in the form of linear combination to perform temperature control. It is a kind of linear control. method, after adding fuzzy control, it can be changed into a nonlinear control method, but the fuzzy parameters of fuzzy control are determined b...
