Abstract

The invention discloses a central air conditioning fuzzy control system and a central air conditioning fuzzy control method. The central air conditioning fuzzy control system comprises central air conditioning equipment (10), a data acquirer (20), a central controller (30), an equipment controller (40) and/or an executor (50), wherein the data acquirer (20) is connected to the central air conditioning equipment (10), and is used for acquiring a plurality of operating parameters of the central air conditioning equipment (10); the central controller (30) is used for receiving the operating parameters acquired by the data acquirer (20), performing fuzzy reasoning according to the operating parameters, performing sharpening processing on reasoned fuzzy control volume, and determining output control volume; the equipment controller (3) and/or the executor (50) are/is connected to the central controller (30), and are/is used for receiving the output control volume determined by the central controller (30), and regulating the corresponding operating parameter according to a control instruction of the central controller (30). According to the central air conditioning fuzzy control system, a multiple input variable and multiple output variable central air conditioning system can be comprehensively controlled.

Description

technical field [0001] The invention relates to the field of central air-conditioning control systems, in particular to a central air-conditioning fuzzy control system and a control method thereof. Background technique [0002] The existing central air-conditioning fuzzy control technology uses single variables such as temperature difference deviation and temperature difference deviation change rate to carry out fuzzy control. The general process is to first collect the current flow rate, supply and return water temperature data, and calculate the temperature difference deviation and temperature difference deviation change rate according to the predetermined formula; Carry out fuzzy processing on temperature difference deviation and temperature difference deviation change rate, and calculate its fuzzy quantity and rate velocity; take temperature difference deviation and temperature difference deviation change rate fuzzy quantity as input parameters, and calculate fuzzy data b...
