Application of Adaptive PID in Temperature Control of Solar-fresh Air System
The solar-fresh air system is a new type of auxiliary heating system that combines solar thermal utilization with fresh air system for indoor ventilation.The solar-fresh air system has the characteristics of large inertia,hysteresis and nonlinearity,and its mathematical model is difficult to establish accurately,and it is difficult to keep the fresh air temperature stable by conventional PID control.In order to solve this problem,an adaptive PID controller for the solar-fresh air system is designed,and the fresh air temperature can be accurately controlled by adjusting the parameters of the PID controller online,which provides another way of thinking to realize the temperature control of the solar-fresh air system.
