%X This paper is to quantitatively study the characteristics of active control of vibrating frequency of a piezothermoelectric circular plate with nonlinear deformation, and the effect of changing temperature of environment and the large amplitude of vibration on the characteristics.The results show that the changing temperature of environment of the plate has influence on the controlled frequency of vibration of the plate by means of piezoelectric voltage. When the controlled voltage is high enough, the effect of vibrating amplitude on the characteristic of voltage-vibrating frequency is not notable.
