发动机主动隔振系统模糊控制

Fuzzy Control System for Active Engine Vibration Isolation

介绍了厚型压电陶瓷作动器与被动悬置串联组成的汽车发动机主动悬置系统,分析了隔振系统的数学模型,采用参数自整定的模糊PID控制方法对系统进行了仿真研究,为实现汽车发动机振动主动控制提供了理论依据和具体实施方法.

An automobile active engine mount system using a piezoelectric actuator and passive mount is discussed.A dynamic analysis model of the engine vibration isolation system is established.The simulating resultsthat base on parameter self-tuning fuzzy PID control strategy are developed.According to fuzzy controlprinciple, the paper provides concrete implementing methods.
