Abstract

Journal of Vibration and Control, Ahead of Print.
This paper investigates the effect of a delayed fractional-order proportional-derivative (PD) controller on the stability and dynamic behavior of an electrostatic micro-actuator. After a brief description of the model, a semi-analytical method is applied ...
