摘　　要：针对新型飞机除冰车加热系统的大惯性、纯滞后、非线性和模型不确定性等特点,提出了一种新的模糊复合控制方法。该方法将基于模糊规则切换的Fuzzy-PID双模控制与参数自整定模糊控制相结合,一方面利用基于模糊规则切换的Fuzzy-PID双模控制器增强系统的鲁棒性和抗干扰性,另一方面利用参数自整定模糊控制器加快系统的响应速度。理论分析和仿真结果表明,所设计的模糊复合控制方法能很好地适应飞机除冰车加热系统数学模型的大幅度变化,具有很大的实用价值。In view of the great inertia, pure time-delay, non-linear and model uncertainty of the heating system in the new aircraft deicing vehicle heating system,a fuzzy compound control method is proposed. It combines the Fuzzy-PID controller using fuzzy switching based on fuzzy rules with the fuzzy controller using self-adjusting parameters. This control method makes use of the merits of the improving robustness and disturbance rejection of Fuzzy-PID controller using fuzzy switching based on fuzzy rules,and speeds up the response process by the fuzzy controller with self-adjustlng parameters. Theoretical analysis and the results of simulation show that this fuzzy compound control method can adapt itself to the great changes of mathematical model in aircraft deicing vehicle heating system and has huge practical value.
