“…Therefore, it is necessary to study a new fuel flow control mode. Linear ultrasonic motor, as a new type motor that can directly drive the load, with high control precision, no electromagnetic interference and simple structure, has broad application prospects in the field of micro precision control, and provides a new way for the realization of the turbofan engine fuel flow control [4][5][6][7]. An important indicator to measure the performance of the fuel supply regulator is the accuracy, and the overshoot is the key parameters reflecting the fuel regulating accuracy.…”

Abstract. The fuel regulator based on the linear ultrasonic motor can effectively control the fuel flow. However, the slip of the actuator in the braking phase will cause the overshoot, so that the fuel regulator can not control the fuel flow accurately. In order to reduce the overshoot, this paper presents the result control method based on the successive approximation and the process control method based on the speed regulation by analyzing the representative form of the overshoot of the regulator and the main cause of the overshoot. The control program is designed and programmed. The experimental results show that the two control methods can greatly reduce the overshoot of the fuel regulator, but the adjustment time has increased. Over comprehensive measure of overshoot and adjustment time, the result control based on successive approximation is better than process control based on speed regulation. The overshoot of the fuel regulator based on linear ultrasonic motor is reduced about 70% compared to that of traditional fuel regulator when the result control based on successive approximation is adopted, which greatly improves the fuel flow control accuracy.

“…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.

“…Various types of USM have been reported in the past three decades. [1][2][3][4][5][6][7][8][9][10][11] With the discovery of new generation piezoelectric materials, i.e., the relaxor-PT ferroelectric single crystals, such as (1Àx)Pb(Mg 1/3 Nb 2/3 )O 3 -xPbTiO 3 (PMN-PT) and (1Àx)Pb(Zn 1/3 Nb 2/3 )O 3 -xPbTiO 3 (PZN-PT), high performance USMs have been developed utilizing their superior piezoelectric and electromechanical coupling properties. 12 In addition, these single crystals have very good actuation performance at low temperatures.…”

We report a face-shear mode ultrasonic motor (USM) made of [011]c poled Zt ± 45° cut 0.24Pb(In1/2Nb1/2)O3-0.46Pb(Mg1/3Nb2/3)O3-0.30PbTiO3 single crystal, which takes advantage of the extremely large d36 = 2368 pC/N. This motor has a maximum no-load linear velocity of 182.5 mm/s and a maximum output force of 1.03 N under the drive of Vp = 50 V, f = 72 kHz. Compared with the k31 mode USM made of Pb(Zr,Ti)O3 (PZT), our USM has simpler structure, lower driving frequency, much higher electromechanical coupling factor, and twice power density. This USM can be used for low frequency operation as well as cryogenic actuation with a large torque.
