The article is mainly devoted to the analysis of the transient process during the phase change of the intra-impulse modulated signal of the system, which is composed of a pair of piezoelectric ceramic transducers. In the introductory part, this article is focused on the most accurate determination of the parameters of electrical equivalent circuit of piezoelectric ceramic transducers commonly available on the market of electrical components and less economically demanding. Based on the determination of these parameters, a system consisting of the piezoelectric ceramic transducer, transmitter -environmentpiezoelectric ceramic transducer, receiver is then assembled and represented by transfer function. This system is subjected to simulation. An intra-impulse modulated signal with phase modulation is connected to the system input. The response to this signal is subsequently analyzed and compared with the real response of a real system. The goal is therefore to verify the suitability of the simulation model and, on the basis of this analysis, to determine the possibility of using specific piezoelectric ceramic transducers for application of intra-impulse modulated signal. As a method of verification, main parameter analysis of a cross-correlation function was selected. Based on this analysis it was found that this method is relevant for this purpose.

“…Several attempts have been carried out to develop the model of the motor. The equivalent circuit was widely used on ultrasonic motor modeling [1]- [6]. But this type of model is a rude modeling method of the dynamic characteristics of ultrasonic motor and cannot be used to design motor's controller directly.…”

n this paper, a study on modeling of a piezoelectric transducer type rotary traveling wave ultrasonic motor (USM) is presented. First a mathematical model and numerical simulation results are achieved. The model is based on the theory of piezoelectricity and physic theory. An experimental model is worked out and compared to the numerical model. The influence of the temperature on characteristics such as the rotational speed of the motor is considered. The speed of the USM is measured at temperature between 17°Cand 50°C. To develop suitable control strategies for the drive, a fuzzy model type Takagi-Sugeno is used. The unknown parameters of the output membership functions are determined by least square method. Experimental data are used to examine the validity of the fuzzy model. Comparison between experimental and calculated data of the fuzzy model indicates that the fuzzy model can well describe the nonlinear characteristics among the frequency of driving voltage and rotating speed.
