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.

这项研究工作旨在研究当压电贴片材料用作悬臂梁的主动振动抑制器的执行器和传感器时，四个非线性特征（即磁滞，饱和度，蠕变和不确定振动）的存在。压电贴片材料的特性考虑到了诸如不同工作频率和电压之类的参数，并测量了主动减振系统中比例-导数-积分控制器激活前后的振动。评估主动振动抑制系统性能的三个主要贡献是，不同的比例-微分-积分控制器调整方法，频率独立和频率相关激励的影响。从结果来看 压电致动器具有所有四个非线性效应，而在传感器特性中仅观察到三个，并且这些效应随着工作频率和电压的增加而显着增加。对于主动振动抑制系统的频率无关的激励，由于饱和效应，除了在500 Hz时，梁的振动衰减从低到较高的激励频率都有改善。在控制器性能方面，与手动方法和Ziegler-Nichols方法相比，比例增益升压方法通过对最高振动衰减百分比的3/5进行评分，显示出最佳性能。对于频率相关的激励，
