| Summary: | In automotive applications, engine mounting is a component used to support the car engine on the chassis and at the same time isolates vibration from engine. Ideally engine mounting system should isolate vibration caused by engine disturbance force at engine speed range and prevent engine bounce from shock excitation. Nowadays, active engine mounting system has been considered as the next generation of engine mountings. The system consists of passive mounting, force generating actuators, sensors, and electronic controllers. It is necessary to design a controller that able to suppress the unwanted vibration by controlling the actuator force. Different control strategies have been proposed, however most of the control approaches are model based control design which requires precise mathematical model of the plant and its parameters. In order to design a simple and robust controller in the field of active engine mounting system, intelligent sliding mode control using natural logarithm sliding surface is proposed. It combines learning capability of artificial neural network and robustness of sliding mode control strategies to develop model-free control design. The effectiveness of the proposed methods is evaluated through simulation and experiment on the lab-scale active engine mounting system. The results show that the proposed controllers able to reduce the engine vibration effectively in the band of frequency of interest from 5 Hz to 30 Hz. |
