Experimental studies on active vibration control of smart plate using a modified PID controller with optimal orientation of piezoelectric actuator

Abstract

This paper presents a design, development and experimental verification of an active vibration control system of aluminum plate. The active structure consists of an aluminum rectangular plate as the host structure, strain gages as the sensor element and a piezoceramic patch as the actuation element. Based on characteristics of the integrated elements with use of the fuzzy optimization strategy based on the pseudogoal function the optimal orientation of piezoelectric actuator is found, and the whole active vibration control system is designed and developed. The active vibration control system is controlled by proportional-integral-derivative (PID) control strategy. Control algorithm was implemented on the PIC32MX440F256H microcontroller platform. In order to prevent it from negative occurrences from derivative and integral terms in a PID controller, the first-order low-pass filters are implemented in the derivative action and in the feedback of integral action. The experiment considers active damping control under periodic excitation. Experiments are conducted to verify the effectiveness of the vibration suppression and to compare the damping effect with different adjustment of PID gains. Experimental results corresponding to the developed active vibration control system are presented. The system suppresses more than 90% of vibration amplitude, which confirms the high level of effectiveness in vibration active damping at the proposed active structure.

Experimental investigation of spillover effect in system of active vibration control

“…In order to achieve periodic excitation, an eccentric pulley is mounted at the tip of the beam (figure 1). Periodic excitation is achieved by the electromotor and is transmitted to the eccentric pulley using a belt [6,11].…”

“…The research of instability of the active vibration control was performed on composite beam using full bridge strain gages for sensor platform and bonding piezoelectric patches for actuator platform. The PID control algorithm is implemented on a 'PIC32-PINGUINO-OTG' board [6,11], with an integrated PIC32MX440F256H microcontroller. The experiment considers vibration control under periodic excitation at the eccentricity pulley.…”

A Self-Tuning PID Control Method for Multi-Input-Multi-Output Nonlinear Systems

“…A new control method of combining a novel positive temperature coefficient material with PID control algorithm was proposed in [24]. A PID-based active vibration control system of an aluminum plate was designed, developed and experimentally verified in [25]. A new control design for an autonomous underwater vehicle was presented in [26].…”

A Comparative Study Based on Different Control Algorithms for Suppressing Multistage Gear Transmission System Vibrations

“…More than this, the meshing vibration will also arouse the transmission shafts generating translational and bending deformations. As shown in Figure 2(b), the blue line 1 1 2 is the original position of the driving transmission shaft in the steady state condition, and the red dashed line 1 1 2 is the position after deformation owing to the vibrations propagation, projecting 1 -axis directions, and 1 , 1 is projective coordinate of point 1 . The distances between the projective points and the coordinate origin can be expressed as follows:…”

“…The vibrations of multistage gear transmission system (MGTS) are closely related to the time-varying meshing stiffness, transmission errors, and meshing impacts [1,2]. The gear meshing vibrations will be transmitted to the whole housing structure via the transmission shafts and supporting parts, which will damage the properties of the entire transmission system seriously.…”
