模糊自适应PID控制器在太阳能干燥温度控制中的应用
Application of fuzzy adaptive PID controller in solar drying temperature control
【摘要】 基于中国农村对特色农副产品干燥设备的需求现状,设计了一种热能辅助型太阳能箱式干燥器。该装置由干燥箱、热风炉和循环系统构成。针对太阳能辅助热能干燥过程参数时变性和模型不确定性设计了一种基于模糊推理的参数自适应P ID控制器。仿真结果表明,该控制器具有理想的动态和稳态以及抗干扰性能,超调量、过渡过程时间等控制性能指标优于传统P ID控制器,能够满足太阳能干燥系统对参数控制的要求。
【Abstract】 At present,the lack of fitting farmer family-type drier in China,a kind of box-style solar drier with accessorial thermal(energy) designed.The drier includes drying box,thermal wind stove and circle system.The thermal parameters of the solar drying with accessorial heat present nonlinear,large-lag,time-variable and model uncertainty in drying process.A kind of fuzzy adaptive PID controller was designed.The simulated results show that the controller has excellent dynamic,steady and anti-jamming performance than traditional PID controller,such as the index of overshoot value and regulating time. It can well meet the temperature(control) requirement of solar drying system.
