The paper describes theoretical and experimental investigation of applying Bouc-Wen model in displacement modeling of piezelectric ring benders. Under the increasing demand for more accurate position control systems, various hysteresis models appropriate for control purpose of mechanical systems have been proposed. Most of these models are based on phenomenological approach, for example: Prandtl–Ishlinskii or Krasnosel’skii-Pokrovskii and other, friction based like Maxwell-slip model. This paper presents a model described in analytical form, called the Bouc-Wen model, appropriate for position control purpose. Paper presents histeresis investigation results of Noliac CMBR05 ring bender under different voltages. Furthermore, article depicts how model was numerically implemented and investigated on dSpace Control System with Matlab Simulink Software for future research on real time position control with inverted hysteresis model.

“…In the local model, the threshold voltage is set by a resistance circuit and displayed in LED segment displays. As the complex electromagnetic environment causes the possibility of error trigger; in order to increase the reliability of over-current protection, a Schmitt trigger circuit has been chosen for the system [9]. The voltage generated by the current sensor is compared with the threshold voltage of the Schmitt trigger circuit.…”

Neutral beam injection is one of the effective auxiliary heating methods in magnetic-confinementfusion experiments. In order to acquire the suppressor-grid current signal and avoid the grid being damaged by overheating, a data acquisition and over-current protection system based on the PXI (PCI eXtensions for Instrumentation) platform has been developed. The system consists of a current sensor, data acquisition module and over-current protection module. In the data acquisition module, the acquired data of one shot will be transferred in isolation and saved in a data-storage server in a txt file. It can also be recalled using NBWave for future analysis. The over-current protection module contains two modes: remote and local. This gives it the function of setting a threshold voltage remotely and locally, and the forbidden time of over-current protection also can be set by a host PC in remote mode. Experimental results demonstrate that the data acquisition and overcurrent protection system has the advantages of setting forbidden time and isolation transmission.

“…There are usually two types of power amplifiers: voltage amplifiers and charge amplifiers [ 9 , 10 , 11 , 12 , 13 , 14 ]. Because voltage amplifiers have the advantages of simple structure and high bandwidth, they have been widely adopted for commercial power amplifiers [ 13 , 15 ]. Many such voltage amplifiers have been proposed by References [ 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 ], and the power amplifier can also be used to estimate the force and displacement of the piezoelectric stack actuator [ 24 ].…”

“…In Reference [ 26 ], a dual amplifier able to deliver a 300 kHz sine wave of 20 Vpp amplitude with 100 nF load is proposed. Aiming at low cost, Reference [ 15 ] designs the power amplifiers by audio power amplifiers, because of their high output current and high frequency bandwidth, and the power amplifiers can drive capacitive loads with the output signal frequencies reaching 20 kHz. Reference [ 27 ] implements an innovative amplifier, using isolation amplifier and subtracting amplifier; the amplifier presents a voltage gain of approximately 100 and an output swing of 200 V. These works in the mentioned referenced papers are innovative; however, some problems still exist: high output noise ripples, high price, low output voltage, or complex circuit structure.…”

In this paper, based on the principles of general operational amplifiers, a high-voltage operational amplifier is developed. Considering the influences of piezoelectric stack actuators on the circuit, a novel structure using the high-voltage operational amplifier as a noninverting amplifier is proposed. Because of the simple circuit principles and the voltage feedback control structure, the proposed power amplifier has the advantages of low noise and small size, and it can be realized by discrete electric elements easily. In the application of precision positioning, a power amplifier using the proposed circuit principles for driving piezoelectric stack actuators is designed, simulated, and tested. The simulated results show that the proposed power amplifier could conform to the theory of the circuit. The experimental results show that the designed power amplifier conforms to the simulation, the bandwidth of the power amplifier is about 57 kHz, and the ripple of the power amplifier is less than 2 mV. Furthermore, the output of the proposed power amplifier maintains the same type of wave within in a large range of frequency, while the input is the sinusoidal or square wave, and the resolution of the mechanism which the power amplifier is applied in is about 4.5 nm. By selecting the critical electronic elements and using feedback control, the proposed circuit structure is able to realize a low-cost and high-performance power amplifier to drive piezoelectric stack actuators flexibly, which is the novel work of the paper.
