“…The red arrow direction in Figure 4 is the direction of friction force, the blue arrow direction is the direction of stator traveling wave motion, and the black arrow direction is the direction of tooth surface motion. The deformation caused by the extension and contraction of the positive and negative polarization zones of the piezoelectric ceramic is the reason for the occurrence of traveling waves in the stator of the ultrasonic motor [8]. sin( )…”

Compared with traditional motors, ultrasonic motors have the advantages of small size and no noise and are widely used in modern technological fields. This article proposes a neural network-based ultrasonic motor control method and optimizes it to address the difficulty of controlling ultrasonic motors. Firstly, the principle and equivalent circuit of ultrasonic motors are studied, and a phase-shifted PWM method suitable for driving ultrasonic motors is proposed. Secondly, to meet the nonlinear characteristics of ultrasonic motors, a NARX neural network that can be used for nonlinear systems is adopted for optimization control. Finally, an experimental platform was built for the experiment, and the results showed that the proposed H-bridge driving circuit has a wide input voltage range. After using the NARX neural network, the output voltage of the H-bridge circuit is more stable, which can provide a stable driving voltage for the ultrasonic motor. It can provide a certain reference value for the application of ultrasonic motors in modern technology.

The object of this study is the process of detection and tracking of air targets. The task being solved is to choose priorities between hardware and software solutions to eliminate structural contradictions in the design of a supporting and rotating device, which at the same time should ensure high speed and accuracy of tracking aerial objects for the optical-electronic station. A prototype of an optical-electronic station was designed and built. The study of the effect of eliminating structural contradictions by hardware and software methods on the accuracy characteristics of the supporting and rotating device was carried out. We have developed original specialized software for testing the accuracy of command execution. A procedure for testing the optical-electronic station has been devised. All conducted tests were performed in compliance with accepted norms and standards. The mechanism of influence of the method of controlling the servo drives of the supporting and rotating device on the characteristics of the optical-electronic station has been established. In this case, the program method has priority. In contrast to existing solutions, the developed software method of controlling the support-turning device makes it possible to exclude stops at the limits of the servo control period and to realize a smooth transition to a new value of the tracking speed. Owing to the improvement of forecasting and synchronization of servo parameters with the period of its control, it was possible to solve the investigated problem by the software method. The mechanism of influence of the inertia of the supporting and rotating device on the characteristics of the optical-electronic station has been established. In this case, the hardware method has priority. The results could be used to improve the characteristics of optical-electronic stations in the detection and high-precision tracking of moving objects in the air environment
