A novel design of traveling wave piezoelectric actuator with a special waveguide is investigated in the paper. Actuator consists of cylinder type waveguide and piezo ceramic ring. Waveguide has conical hole inside. Such configuration of the waveguide allows increasing amplitudes of the traveling wave vibrations. Electrodes of piezoceramic ring are divided into four equal sections. Four electric signals with shifted phases by π/2 are used for the excitation. Numerical simulation was carried out to optimize the shape and dimensions of the waveguide and to maximize oscillation amplitudes at the contact surface of the waveguide. Mathematical model of the contact interface between stator and rotor was developed. A prototype piezoelectric actuator was made and experimental investigation was performed. Results of numerical and experimental investigation are discussed.

“…According to the vibration mode of the stator, piezoelectric motors may be classified into traveling wave type motors [12][13][14][15][16], standing wave type motors [17][18][19][20], and composite vibration modes type motors [21][22][23][24][25][26][27][28]. The first type, more suitable for producing rotary motion, is the most common and classic one as it has been successfully used in the camera auto-focus system.…”

“…Additionally, the adoption of advanced controllers, such as sliding mode control, fuzzy theory-based control, and adaptive control, requires many adjustable elements as well as an exact mathematical model. [6][7][8][9][10][11][12][13][14] Ultrasonic motors based on a friction force drive have been applied to these controllers, as an ultrasonic actuator has numerous advantages. These include high driving force, high holding force without any power supply, high precision, low magnetic noise, vacuum compatibility, rapid response, compact mechanism, and silent operation.…”

This paper presents a design and control system for an XY stage driven by an ultrasonic linear motor. In this study, a hybrid bolt-clamped Langevin-type ultrasonic linear motor was manufactured and then operated at the resonance frequency of the third longitudinal and the sixth lateral modes. These two modes were matched through the preload adjustment and precisely tuned by the frequency matching method based on the impedance matching method with consideration of the different moving weights. The XY stage was evaluated in terms of position and circular motion. To achieve both fine and stable motion, the controller consisted of a nominal characteristics trajectory following (NCTF) control for continuous motion, dead zone compensation, and a switching controller based on the different NCTFs for the macro- and micro-dynamics regimes. The experimental results showed that the developed stage enables positioning and continuous motion with nanometer-level accuracy.
