Intelligent control method for solar energy and air source heat pump combined heating system

The invention provides an intelligent control method for a solar energy and air source heat pump combined heating system based on model predictive control (MPC), and relates to solar radiation prediction, building load prediction and room temperature prediction. The combined heating system is composed of a solar heat collector, a solar circulating pump, a heat storage water tank, a solar heating pump, an air source heat pump and a heat supply circulating pump. Firstly, data of system operation parameters and indoor and outdoor environment parameters are collected, and a productivity mathematical model and a heat storage mathematical model of a solar heat collection system and COP and energy consumption mathematical models of an air source heat pump are established; performing sensitivity analysis on the environmental parameters, the building thermal parameters and the internal disturbance parameters to extract key influence factors, establishing a hourly solar radiation intensity prediction model and a buildi
