A Constant Air Flow Controller Based on Interval Type-2 Fuzzy PID Controller
摘要
In order to improve the sampling accuracy and the adaptability to different loads, a constant air flow controller based on closed-loop control is designed and realized. The mathematical model of this constant air flow controller is established, and an interval type-2 fuzzy PID controller is designed. The stability of the closed-loop constant flow controller is analyzed theoretically. Constant flow control simulations and experiments using PID controller and the interval type-2 fuzzy PID controller are done. The simulation and experiment results show that the constant air flow controller based on interval type-2 fuzzy PID controller has satisfied performance and adaptability to different loads.
