Abstract

The embodiment of the invention discloses a parameter setting method and device, a storage medium and a parameter setting unit, and belongs to the field of thermal control. The method comprises the steps of creating a model library for controlled objects under different working conditions, wherein each model in the model library corresponds to one working condition; selecting an optimal model matched with the current data of a coordinated control system from the model library; generating an optimal control parameter of a prediction controller according to historical data, the optimal model andan improved differential evolution algorithm; and providing the optimal control parameter for the prediction controller. According to the embodiment of the invention, parameter setting can be performed in combination with the improved differential evolution algorithm, manual parameter setting is not needed, the accuracy of control parameters can be improved, and the efficiency of parameter setting can also be increased.

Description

technical field [0001] The embodiments of the present application relate to the field of thermal control, and in particular to a parameter setting method, device, storage medium and parameter setting unit. Background technique [0002] Since predictive control was proposed, it has been increasingly applied to various industrial fields, and it can be found in transportation, civil engineering, energy, aerospace and medical treatment. As far as the field of thermal control is concerned, in the face of today's large-capacity, complex and uncertain thermal objects, the early PID (Proportion Integration Differentiation, proportional-integral-differentiation) control system obviously cannot meet the needs of the rapid development of the power industry. The predictive controller has a wide range of engineering applications in thermal power units because it can predict the changes of the controlled object, adjust the controlled object in advance, and has a strong ability to deal wit...
