Abstract:
In this article, derivation of a nonlinear model for a micropipe conveying fluid which is excited with a piezoelectric actuator as well as control of this system is studied. The governing equations are derived using Hamilton’s principle. The difference between the equations in micro-scales and macro-scales is stablished using modified couple stress theory. The nonlinear terms of equations also arise from mid-plane stretching. After this derivation, a frequency analysis is done on the model. In addition, the effective parameters on the peak value of the response are also studied. And finally a fuzzy sliding mode controller is designed for the input voltage of the system.
