摘要
温度是影响PEMFC最重要的因素之一,有效的温度控制可以保证电池的高性能,延长电池的寿命。首先根据PEMFC的实际应用经验模型建立了温度模型,设计了一种通用的变论域模糊PID控制器,用于实现对电堆的温度控制。变论域的本质是通过伸缩因子来实时调整模糊论域,进而动态调节PID的3个参数,因此变论域模糊PID控制器显现出更高的控制精确度。最后对温度模型和所设计的控制器进行仿真分析,仿真的结果表明:变论域模糊PID温度控制器不仅可以有效减少电池系统的超调,具有很强的抗干扰能力和鲁棒性,可以用来对电池的温度控制。
Temperature is one of the most important factors affecting PEMFC. Effective temperature control can ensure the high performance of the battery and extend the life of the battery. The temperature model is established based on the practical application model of PEMFC. A general variable domain fuzzy PID controller is designed to realize the temperature control of the stack. The essence of the variable universe is to adjust the fuzzy domain in real time through the scaling factor, and then dynamically adjust the three parameters of PID, so that the variable domain fuzzy PID controller shows higher control precision. Finally, the temperature model and the designed controller are simulated and analyzed.Finally, the temperature model and the designed controller are simulated and analyzed. The simulation results show that the variable domain fuzzy PID temperature controller can not only effectively reduce the overshoot of the battery system, but also has strong anti-interference ability and robustness. It can be used to control the temperature of the battery.
