Problems solved by technology
However, when the fuzzy PID control algorithm is applied to a nonlinear time-varying large lag system, if the control period is not selected properly, the fuzzy PID control algorithm will also diverge and not converge, and it is still necessary to manually adjust the PID control parameters for different types of systems. Fuzzy rules, poor adaptability

The invention provides a control method of an air conditioning system, a control device, a storage medium and the air conditioning system. The air conditioning system is a hysteresis system, the air conditioning system comprises the control device and an air conditioner, and the control device comprises a processor. The control method comprises the following steps that an operation trend of outputparameters of the air conditioner is subjected to fitting processing through the processor to obtain trend curve data; the processor predicts a predicted output parameter of the next control period according to the trend curve data under the condition that current control parameters are kept unchanged; and the processor determines that the predicted output parameter is stable, and then operates afuzzy PID control algorithm according to the deviation between the predicted output parameter and a set value. The mechanism of self-adaptive adjustment of the control period is introduced on the basis of the fuzzy PID control algorithm, and the stable state after each time of adjustment of the system is predicted in real time according to the operation data of the air conditioner, and a reasonable control period is selected in a self-adaptive mode, so that the control effect and the stability of the fuzzy PID control algorithm are improved.
Description
technical field [0001] The present invention relates to the technical field of air conditioning, in particular to a control method of an air conditioning system, a control device, a computer-readable storage medium and an air conditioning system. Background technique [0002] PID (proportion, integral, differential) control is used in most HVAC frequency conversion speed control systems. Traditional PID control has the characteristics of simple structure, easy implementation, and simple calculation process, so it has been widely used. However, in practical applications, traditional PID control requires a complex and time-consuming parameter tuning process, and a large number of online running tests are required. If the parameters are not selected properly, it will lead to problems such as low control accuracy, poor stability, and serious overshoot. In the face of large systems with nonlinear, time-varying, large lag and other characteristics, there will be certain limitatio...
