“…A single piezoelectric element was employed as an actuator and a sensor simultaneously. Pelletier [ 22 ] and Qiu [ 23 ] applied a piezoelectric self-sensing actuation in active vibration control in the same way. The piezoelectric transducer (PZT) can be also used as a vibration damper [ 24 , 25 ].…”

The vibration isolation system is now indispensable to high-precision instruments and equipment, which can provide a low vibration environment to ensure performance. However, the disturbance with variable frequency poses a challenge to the vibration isolation system, resulting in precision reduction of dynamic modeling. This paper presents a velocity self-sensing method and experimental verification of a vibration isolation system. A self-sensing actuator is designed to isolate the vibration with varying frequencies according to the dynamic vibration absorber structure. The mechanical structure of the actuator is illustrated, and the dynamic model is derived. Then a self-sensing method is proposed to adjust the anti-resonance frequency of the system without velocity sensors, which can also reduce the complexity of the system and prevent the disturbance transmitting along the cables. The self-sensing controller is constructed to track the variable frequency of the disturbance. A prototype of the isolation system equipped with velocity sensors is developed for the experiment. The experiment results show that the closed-loop transmissibility is less than −5 dB in the whole frequency rand and is less than −40 dB around, adding anti-resonance frequency which can be adjusted from 0 Hz to initial anti-resonance frequency. The disturbance amplitude of the payload can be suppressed to 10%.

The present work aims to design a new polarized piezoelectric sensor actuator. This sensor actuator not only can achieve sensing and execution at the same time, but also has the advantages of small size and high integration. A mathematical model of stack displacement with input voltage and number of layers was established. The relationship between the charge generated by quartz crystal and external force was numerically analysed. The static and modal analysis of the structure were carried out to obtain the measured force range and the maximum working frequency. The transient simulation is used to verify the follow-up law of the actuator to the alternating signal. The Electric field interference analysis of the piezoelectric sensor actuator was performed to eliminate the interference from the electric field generated by the actuator. The results show that the measured force range of the actuator is up to 1 kN, with the maximum working frequency is 1000 Hz, and the actuator can follow the drive voltage signal well, with an almost negligible electric field interference in the sensor part. This paper provides a new method and theory for the study of self-sensing actuators.
