Keywords: MEMS; micropipe; piezoelectric; couple stress theorem; Hamilton’s principle; sliding mode controller.


In this article, derivation of a nonlinear model for a micropipe conveying fluid which is excited with a piezoelectric actuator as well as studynig the control of this system. 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. Finally a sliding mode controller is designed for the input voltage of the system. Using this type of controller, it has been observed that the behavior of the system can be improved impressively.
