Time-delayed velocity feedback is taken into consideration in the DC and AC driving voltage of the folded-MEMS comb drive resonators and the single degree of freedom model of the folded-MEMS comb drive resonators under the influence of time-delayed control is presented. This paper feedback from the velocity with small vibration amplitude to the electricity driving force and approximate the expression with the Taylor expansion. The method of multiple-scales is used to obtain the amplitude-frequency response equation of the system under the influence of time-delay parameters. The change of time-delayed parameter in the system nonlinear resonance result in jumping phenomena when the driving frequency is in the vicinity of resonance frequency. The resonance frequency and nonlinear characteristics of softening or hardening vary under conditions with different physical parameters such as DC and AC voltage. Stability region and vibration amplitude of the system with different physical parameters can be controlled by changing the time-delay parameters. The conclusion that the positive time-delayed control gain make the system instable and the negative time-delayed control gain lead to the disappearance of jumping phenomena is verified by the computation with numerical method.
