Control Method Research Of Piezoelectrical Intelligent Structure Based On Neural Network

This paper made a research on control method of piezoelectrical intelligent structure, using the neural network method which is in forward position of field of automotive control to control a flexible beam. First, driving equation of the smart beam was developed ,then, the conduction equation was developed,at last ,the integrate control equation was developed.Between the actuator and the sensor,a BP neural network was added as the controller, numeric simulation was made to test the effectiveness of this method.The result showed that the method has apparent effectiveness in suppressing the vibration of the smart beam. For deeper research of this method, another neural network method was designed to control the smart beam for discussion.
