“…The reason why it is so attractive is that it can provide perfect performances in terms of fast responses, high precision, limitless resolution, etc. However, these superior performances can be severely affected by several factors (Jian, 2019;Ahmad Mazlan and MohdRipin, 2016;Feng, 2017), and thus the degraded performances may restrict the further applications of the piezoelectric stage.…”

Purpose The problem of parameter identification for biaxial piezoelectric stages is still a challenging task because of the existing hysteresis, dynamics and cross-axis coupling. This study aims to find an accurate and systematic approach to tackle this problem. Design/methodology/approach First, a dual-input and dual-output (DIDO) model with Duhem-type hysteresis is proposed to depict the dynamic behavior of the biaxial piezoelectric stage. Then, a systematic identification approach based on a modified differential evolution (DE) algorithm is proposed to identify the unknown parameters of the Duhem-type DIDO model for a biaxial piezostage. The randomness and parallelism of the modified DE algorithm guarantee its high efficiency. Findings The experimental results show that the characteristics of the biaxial piezoelectric stage can be identified with adequate accuracy based on the input–output data, and the peak-valley errors account for 2.8% of the full range in the X direction and 1.5% in the Y direction. The attained results validated the correctness and effectiveness of the presented identification method. Originality/value The classical DE algorithm has many adjustment parameters, which increases the inconvenience and difficulty of using in practice. The parameter identification of Duhem-type DIDO piezoelectric model is rarely studied in detail and its successful application based on DE algorithm on a biaxial piezostage is hitherto unexplored. To close this gap, this work proposed a modified DE-based systematic identification approach. It not only can identify this complicated model with more parameters, but also has little tuning parameters and thus is easy to use.

Heating, ventilating and air conditioning (HVAC) system is one of the major sources for the vehicle noise and vibration, which subsequently contribute to the bad acoustical environment. The components of the HVAC system can produce a significant level of vibration during the operation and contributed to an unwanted noise. As the vibration of HVAC components get worse, it will be transferred to other components and excites the natural frequencies of the HVAC system. Natural frequencies of the components are depending on the mass and stiffness of the HVAC components and the value can been modify using these two parameters. This study is focusing on the specific type of HVAC noise and vibration problem and the counter measure has been perform by implementing the structural dynamic modification (SDM) method to the air conditioning (AC) pipe. The lab-scale of the vehicle HVAC system is set up to represent the actual HVAC system with the real vehicle operation. Noise and vibration of the HVAC system in the system level are measured and compared. From this data, the Dynamic Vibration Absorber (DVA) is designed and applied at the AC pipe of the HVAC system. The result shows that, the natural frequency of the AC pipe can be shifted which resulting a wide effective frequency range of 100-500 Hz. The effect of DVA on the HVAC system is observed during operation whereby a significant vibration attenuation has been achieved for operating frequency range of 100-300 Hz.

This research work aims to investigate the presence of four nonlinear characteristics (i.e., hysteresis, saturation, creep, and uncertainty vibration) when a piezoelectric patch material acts as an actuator and sensor for the active vibration suppression of a cantilever beam. The parameters such as different operating frequencies and voltages are taken into account for the piezoelectric patch material characterization and the vibration before and after activation of a proportional–derivative–integral controller in an active vibration suppression system are measured. The effect of different proportional–derivative–integral controller tuning methods, frequency independent, and frequency dependency excitations are the three main contributions to evaluate the performance of active vibration suppression system. From the results, the piezoelectric actuator posed all the four nonlinearity effects while only three are observed in the sensor characteristics, and these effects increased significantly with the increase of operating frequencies and voltages. For the frequency-independent excitation of the active vibration suppression system, the vibration attenuation of the beam shows an improvement from low to higher excitation frequency, except at 500 Hz because of the saturation effect. In terms of controller performances, the proportional gain step-up method shows the best performance by scoring 3/5 of highest vibration attenuation percentages compared with manual and Ziegler–Nichols methods. For the frequency-dependent excitation, the effective frequency range for the active vibration suppression system is determined between 75 and 245 Hz with the highest vibration attenuation of 79.60% occurred at the second natural frequency of the beam.
