In dynamic viscoelastic measurement, accurate control of strain (or displacement) is one of the most important functions because the strain becomes dominant in viscoelasticity as it increases. However, it is difficult to achieve the accurate strain with commonly-used control methods when the specimen should be deformed largely. This is because the oscillation profile is distorted by the nonlinear viscoelastic response from the specimen and it produces the phase lag and gain loss in the control. In order to solve these problems, a viscoelastometer using a repetitive control was proposed in our previous work, and the applicability has been discussed in linear viscoelastic measurement. In this paper, we examine the applicability of proposed method to nonlinear viscoelastic measurement.
