摘要
针对空调系统的参数不确定性以及模型不精确性,研究一种混合参数自调整模糊PID控制策略,将直接控制型模糊控制器、增益调整型模糊控制器和传统的PID控制器相结合,共同组成自调整模糊PID控制器,以提高控制器的控制性能和整个系统的鲁棒性。仿真结果表明,采用该控制方法可取得良好的控制效果,并进一步证实理论分析的正确性。
According to air-conditioning system＇s shortcomings including parameter uncertainty and model imprecision, the paper introduces a mixed parameter self-adjusted fuzzy PID control method. The method combines the direct-action fuzzy controller and the gain-tuning fuzzy controller with traditional PID controller, to improve the control system＇s performance and robustness. Simulation result shows the control method has good effect, and could further prove its theoretical analysis.
