ABSTRACT: In this paper, the
influence of physical parameters on the width of saturated control frequency
band and the influence of time delay parameters on the stability of saturated
control system are studied. The analytical solution of the motion equation of
the system when the main resonance and the 1:2 internal resonance occur
simultaneously is obtained by multiple scale method, experimentally measured
natural frequencies of nonlinear beams. The effects of excitation amplitude,
delay feedback coefficients and nonlinear coefficients on saturation control
are investigated. The results of the study show that the bandwidth of the
saturation control can be increased by increasing the value of the external
excitation, the nonlinear coefficients enhance the nonlinear phenomena of the
system.
