This paper presents a vibration control method for the suppression of robotic arm. To understand causes in six-axis manipulator and then eliminate through an effective method, structure can be divided into two parts. First, variational mode decomposition (VMD) Hilbert–Huang transform (HHT) algorithm are integrated to analyze signal extract characteristics. Second, smooth trajectory planning is ...

This paper presents experimental investigations into the development of hybrid input shaping and PID control for vibration suppression and input tracking of a flexible robot manipulator. Initially, a PID controller is developed for control of rigid-body motion of the system. This is then extended to incorporate a feedforward controller based on input shaping techniques for vibration control. Ex...

Abstract: In this paper, we developed an approach for active vibration control of flexible rectangular plate structures using control theory. The flexible rectangular plate system is firstly modelled and simulated via a finite element method; and secondly, a new type of modelling method, and the state-space model are involved in the development of the equation of motion in state-space, which is...

The objective of the work reported in this paper is to investigate the development of hybrid iterative learning control with input shaping for input tracking and end-point vibration suppression of a flexible manipulator. The dynamic model of the system is derived using the finite element method. Initially, a collocated proportional-derivative (PD) controller utilizing hub-angle and hub-velocity...

Orthogonal Eigenstructure Control (OEC) is a novel control method that can be used for active vibration cancellation. OEC is an output feedback control method applicable to multiple-input, multiple-output linear systems. In this paper, application of OEC for active vibration cancellation in a plate is presented. A steel plate clamped at four edges is used as a test plate and piezoelectric actua...

This paper presents an investigation into the comparative performance of intelligent system identification and control algorithms within the framework of an active vibration control (AVC) system. Evolutionary Genetic algorithms (GAs) and Adaptive Neuro-Fuzzy Inference system (ANFIS) algorithms are used to develop mechanisms of an AVC system, where the controller is designed on the basis of opti...

Directing at the problem of torsional vibration occurred in the start-up procedures of long shaft drive transmission existed in printing equipment, we raised a variable structure control method based on Variable parameters fuzzy. The method not only displays feature of traditional non-linear variable structure control like nondeference derivation, planning the dynamic process and good capacity ...

Significant levels of undesired vibration and noise are inherent in transport and combat vehicles, particularly in helicopters and propeller aircraft. Therefore, it is important to investigate techniques that reduce vibration and noise in the cabin to improve habitability, effectiveness, and safety for passengers. In addition, continuous exposure may lead to long-term physiological effects. In ...

A series of wind tunnel model tests and theoretical analyses were conducted to investigate torsion excitation, response and vibration suppression of wind-excited buildings. An aeroelastic model for pure torsion vibration was developed and the aeroelastic test results were compared with those obtained by other Wind tunnel test techniques. The comparison and practice indicated that this type of m...

Dynamics of multi-link manipulators with flexible links include complex high-order equations which make their control problem very challenging. This paper presents a new method for simultaneous motion and vibration control of a twolink flexible manipulator using H2/H∞ control. A multi-element finite element model of the manipulator is casted into the generalized plant model, and H2 and H∞ contr...
