Control system and method of floor heating temperature based on particle swarm optimization algorithm

Abstract

The invention discloses a control system and method of floor heating temperature based on a particle swarm optimization algorithm. The method comprises the following steps of: establishing a fuzzy reasoner by using the particle swarm optimization algorithm; calculating the temperature deviation and the variation rate of the temperature deviation after collecting the temperature in the room according to the preset temperature and the collected temperature; calculating parameters of a PID controller according to the temperature deviation, variation rate of the temperature deviation, and fuzzy reasoner; controlling the heating time of a regulating valve by the PID controller according to the temperature deviation and the parameters of the PID controller. The control system and method of floorheating temperature adopts the particle swarm optimization algorithm to establish the fuzzy reasoner. Therefore, the obtained fuzzy reasoning table is more accurate. The control system can better reflect the relationship between temperature changes and control time in different rooms. Therefore, the control system can improve the accuracy of the floor heating temperature control, and make the user more comfortable and more energy efficient. At the same time, the control system reduces the difficulty of parameters adjustment, and reduces the influence of subjective factors. The control systemcan be widely used in the field of floor heating temperature control.

Description

technical field [0001] The invention relates to the field of floor heating temperature control, in particular to a floor heating temperature control system and method based on a particle swarm optimization algorithm. Background technique [0002] Floor heating is the abbreviation of radiant floor heating. It uses the whole ground as a radiator, heats the whole ground evenly through the heat medium in the radiant layer of the floor, and uses the heat storage and heat radiation of the ground itself to conduct from bottom to top to achieve The purpose of heating. [0003] As a heating method that has gradually emerged in China in recent years, underfloor heating uses the control panel installed on the wall as the main control medium. When the user uses floor heating, the indoor temperature can meet the user's comfort requirements by turning on the switch and setting the temperature of the electric heating. Floor heating is a slow-heating heating tool, and it relies on electri...

AI Technical Summary

Problems solved by technology

Floor heating is a slow-heating heating tool, and it relies on electricity or natural gas for heating, often due to inaccurate temperature control, resulting in waste of resources and affecting user experience

The existing technology controls the temperature through the fuzzy PID controller, but because the fuzzy inference rule table used is immutable, it cannot accurately reflect the relationship between different temperature differences and the parameters of the PID controller, so it is impossible to further quickly and accurately control the temperature of the room

At the same time, since the design of the fuzzy PID controller involves many parameters that need to be determined subjectively, and lacks a systematic design method, it is difficult to manually adjust the parameters of the controller only by manual experience.
