摘　　要：太阳能-新风系统是将太阳能热利用与新风系统相结合,用于室内进行通风换气的新型辅助供暖系统。太阳能-新风系统具有大惯性、滞后、非线性的特点,其数学模型难以精确建立,常规PID控制很难使新风温度保持平稳状态。为解决这一问题,设计了用于太阳能-新风系统的自适应PID控制器,通过在线调整PID控制器的参数来精准控制新风温度,以期为实现太阳能-新风系统温度控制提供另一种思路。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 solarfresh 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.
