Simulation Test Method of Temperature Controller Based on Transfer Function

Abstract

The invention relates to a temperature controller simulation testing method based on a transfer function. A computer is connected with a data acquisition board card; a digital quantity interface and an analog quantity interface of the data acquisition board card respectively receive the digital quantity and the analog quantity of a to-be-tested temperature controller; the computer is provided with a temperature display interface; a temperature value outputted by the data acquisition board card is inputted in the to-be-tested temperature controller; computer software and the data acquisition card form a controlled object of the to-be-tested temperature controller; the controlled object and the to-be-tested temperature controller form a simulated closed-loop control system to test and correct parameters of the to-be-tested temperature controller. The controlled object controlled by the to-be-tested temperature controller is simulated, the analogue simulation testing on a to-be-tested system can be performed any time any where, a lab capable of controlling the temperature needs not to be invested on a large scale, the simulation testing reliability is high, the testing process is fast, and the energy consumption is low.

Description

technical field [0001] The invention relates to the field of automatic control and air conditioning, in particular to a temperature controller simulation test method based on transfer function. Background technique [0002] With the rapid development of the national economy, the field of control has been widely concerned by people. In the field of temperature controller simulation, people need to test the controller during the research and development process of the new temperature controller, but the temperature controller test requires an adjustable A room with air temperature, such a room requires a lot of investment, and the inertia coefficient and time lag constant of the room are fixed and cannot be adjusted. People urgently need a faster, more accurate and more convenient system to simulate various actual environments. [0003] As temperature controllers are widely used in modern industrial control systems, more and more attention has been paid to the development and...
