Active vibration control of a flexible beam using a non-collocated acceleration sensor and piezoelectric patch actuator

“…For example, the appendages of the large flexible space structures (LFSS) and space robotic systems usually have very low damping ratios and stiffness, so unwanted vibrations of the systems will be caused by external disturbances [2]. In order to meet the need for accurately pointing antenna and high endposition accuracy of the robotic arms, the issue on active vibration control for this kind of systems is more important than ever [3]. The challenging problem of active vibration control for such flexible beam systems must be solved.…”

Experimental Comparison Research on Active Vibration Control for Flexible Piezoelectric Manipulator Using Fuzzy Controller

“…Space robots are usually made of lightweight materials to help them launch. They usually have very low damping ratios, high dimensional order and parameter uncertainties in dynamics, thus, the unwanted vibrations of the flexible links will be unavoidable [2]. Thus, it is necessary to control lightweight flexible structures, which implies that structural flexibility can no longer be ignored [1,2].…”

“…There are numerous control techniques, both classical and modern, which can cope with the vibration suppression of flexible structures with piezoelectric ceramics (PZT) patches as distributed sensors and actuators [1][2][3][4][5][6][7][8][9][10][11][12]. These techniques are involved in the application of smart materials, featuring piezoelectric actuators and sensors, to the flexible structure to suppress unwanted vibration.…”

A Fast Adaptive Artificial Neural Network Controller for Flexible Link Manipulators

“…With recent developments in sensor/actuator technologies, many researchers have concentrated on control methods for suppressing vibrations of flexible structures using smart materials such as shape memory alloys (SMA) [33], magnetorheological (MR) materials [34], electrorheological (ER) materials [35], piezoelectric transducers (PZT) [36][37][38][39], or using positive position feedback (PPF) to suppress the vibration amplitude of nonlinear systems [40], etc.…”
