Heat pump system control method and device

Abstract

The invention provides a heat pump system control method and device which are applied to the technical field of system control. The method comprises the steps of after obtaining a current control value of a control parameter vector, a current state value of a system state vector and a target state value, firstly determining a control parameter calculation matrix corresponding to the current state value; and determining a control parameter adjustment vector according to the current state value, the target state value and the control parameter calculation matrix, and finally adjusting the control parameter vector based on the current control value and the control parameter adjustment vector so as to enable the system state vector to reach the target state value. According to the heat pump system control method, a manual adjusting mode in the prior art can be replaced, the multiple control parameters in the heat pump system can be adjusted at the same time, and compared with the prior art, the adjusting time consumption can be effectively shortened, and the adjusting efficiency of the heat pump system can be remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of system control, and in particular relates to a heat pump system control method and device. Background technique [0002] The heat pump system is widely used in various equipment such as air conditioners, refrigerators, and thermodynamic test benches. It is one of the key systems for these equipment to operate normally and achieve the intended functions. The system state parameters such as condensing pressure and pre-compressor superheat are accurately controlled to ensure the good performance of the heat pump system. [0003] In the existing technology, the control and adjustment of the heat pump system mostly rely on experience and are done manually. Because the heat pump system has the characteristics of strong nonlinearity, long hysteresis time, and a large number of control parameters and state parameters, it is often difficult to adjust a single control parameter.

[0003] In the existing technology, the control and adjustment of the heat pump system mostly rely on experience and are done manually. Because the heat pump system has the characteristics of strong nonlinearity, long hysteresis time, and a large number of control parameters and state parameters, it is often difficult to adjust a single control parameter. It will cause changes in multiple state parameters. Therefore, by manually adjusting each control parameter of the heat pump system until the state parameters of the heat pump system reach the expected value, it often takes a long adjustment time and the adjustment efficiency is low.
