摘要
针对中央空调冷温水变流量控制系统的非线性、大滞后及时变等特点,将常规的模糊控制与经典的PID控制相结合,设计了一种模糊PID控制器。仿真结果表明,该控制器能有效改善系统的超调量、调节时间、控制精度和鲁棒性。
Aiming at the characteristics of chiller-heater＇s variable flow control of central air-conditioning which are nonlinear,strong inertia,time-variant and pure delay,a fuzzy-PID control was designed based on combination of the conventional fuzzy control with the classic PID control.The simulation results showed that this controller could effectively improve the system overshoot,settling timing,control precision and robustness.
