“…A feedback controller based on a reduced model can destabilize the residual modes. In function of sensor position the feedback can excite the un-modeled state of system (control spillover), and the sensor signals are contaminated by the residual modes (observation spillover) and degrade the active vibration system efficiency (Dong et al 2014;Jovanović et al 2014). Some methods for reduction of spillover effects are discussed by (Mei & Mace 2002;Kim & Inman 2001).…”

In this paper, the problem of vibration suppression of a smart composite plate with bonded piezoelectric patches is considered. A higher order plate model is used for finite element modeling of the plate and the PID controller is used to generate control voltage command to the piezo actuators from the piezo sensors data. Derived formulation and the control algorithm is implemented in a finite element (FE) code and the FE modeling results are verified using available results of previous studies. The effect of control gain on the vibration suppression characteristics is studied. Furthermore, since FE modeling reduces the order of the real problem, the problem of un-modeled residual modes on the so-called spillover effect is investigated.

“…Flexible beam elements are distributed parameter systems with infinite Degrees of Freedom (DoF). The active vibration control generally requires a low-order mathematical model of the system containing a limited number of DoF [6]. In particular, care must be taken so that the control of low-frequency modes does not affect the stabilization of high-grade modes, since sensors and actuators have limited bandwidth [7,8].…”

“…It is very important to specify the sensor and actuator position optimally to keep the control capability at maximum. Otherwise, control spillover and observation spillover may occur, and this will affect the efficiency of the control system [6].…”

The aim of this study is to design a Linear Quadratic Regulator (LQR) controller for the active vibration control of a smart flexible cantilever beam. The mathematical model of the smart beam was created on the basis of the Euler-Bernoulli beam theory and the piezoelectric theory. State-space and finite element models used in the LQR controller design were developed. In the finite element model of the smart beam containing piezoelectric sensors and actuators, the beam was divided into ten finite elements. Each element had two nodes and two degrees of freedom were defined for each node, transverse displacement, and rotation. Two Piezoelectric ceramic lead Zirconate Titanate (PZT) patches were affixed to the upper and lower surfaces of the beam element as pairs of sensors and actuators. The location of the piezoelectric sensor and actuator pair changed and they were consecutively placed on the fixed part, the middle part, and the free end of the beam. In each case, the design of the LQR controller was made considering the first three dominant vibratory modes of the beam. The effect of the position of the sensor-actuator pair on the beam on the vibration damping capability of the controller was investigated. The best damping performance was found when the sensor-actuator pair was placed at the fixed end.

“…Several studies found this method can achieve varying levels of success in the AVS applications ( Åström and Hägglund, 2004;Yatim and Darus, 2014). For example, Jovanović et al (2014) used the Z-N method to investigate the spillover effect of the AVS system on a composite beam and the vibration was reduced up to 94%.…”

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.
