This paper focuses on the change of displacement of Electrostatic Linear Comb Actuator (ELCA) while considering the influence of a driving frequency. A new method for determining the equivalent dynamic parameters such as stiffness, vibrating mass, and air damping factor in motion direction of shuttle (i.e. in y-direction) is proposed, thence establishing and solving the differential motion equation of shuttle aims to achieve a typical displacement formula. Theoretical and simulation results show that the ELCA works stably in the range of frequency from 1 to 24 Hz with displacement amplitude error of 10% and driving voltage is a square wave. Moreover, the range of driving frequency for the ELCA can be extended up to 1 kHz with displacement amplitude error of 10% and the shape of driving voltage is a harmonic sine wave function. © 2019, Springer Nature Switzerland AG.
