“…The internal disturbance was based on the input disturbance from the vibration tool, according to a previous study. 31 The internal disturbance model was a sine wave signal with an amplitude (F 0 ) and excitation frequency (ω) of 20 N and 200 Hz, respectively. In this study, the external disturbances that had been introduced were represented by the external forces implied to the system.…”

“…Meanwhile, Abdullah et al 30 analysed the control scheme with the feedforward model to eliminate the disturbances in the motion control of a mobile manipulator. This control scheme was also used by Mazlan et al 31 to reduce the disturbances on the sander-arm system. The PD and AFCCA control schemes were investigated and it was found that PD increased the transmitted vibration to the system, while, for the system using the AFCCA scheme, a linearly decreasing trend of vibration was achieved.…”

This paper focusses on the study of vibration attenuations for suspended handle models that are generated from power tools using an intelligent active force control (AFC) tuning strategy. Four types of control schemes are comparatively evaluated in suppressing the vibration of the handle, such as proportional-integral-derivative (PID), PID-AFC-crude approximation (AFCCA), PID-AFC-fuzzy logic (AFCFL) and PID-AFC-iterative learning method (AFCILM) control schemes. In all control schemes, the estimated counter force is generated from the actuating force and appropriate estimated mass M* that has been intelligently tuned to counter the system disturbances. The disturbances are modelled based on the power tools vibration (i.e., internal disturbance) and uncertainties during the operation (i.e., external disturbances). The study shows that the AFCCA scheme demonstrates the best performance when the M(CL) is tuned at 0.04 kg. For the AFCFL control scheme, the best response is obtained for the membership function of trapezoidal shape with M(FL) of 0.0403 kg, while for AFCILM control scheme, the best response is achieved when M(ILM) is tuned to 0.04 kg, with both parameters (A and B) set at 0.6. Overall, PID-AFCCA scheme shows the best performances for all of the case studies, followed by PID-AFCFL and PID-AFCILM. The findings of this study can benefit the power tool manufacturers and provide the basis of effectively intelligent controller design for the power tools application.

“…Manuscript to be reviewed Computer Science hand or the arm) and the required levels of accuracy determine the modeling approach to be used. For example, in (Mazlan and Ripin, 2015) a two degree of freedom (DOF) model was adopted while some higher DOF models can be found in (Kamalakar and Mitra, 2018). A precise representation of different impulsive tools and their working postures and the directions of the applied hand force is illustrated in (Dong et al, 2015).…”

“…Thus, the vibration suppression should be significant and urgent to decrease the damage to the operators. Mazlan and Ripin [6] established a three-degree-of-freedom dynamic model of the orbital sander. There were also some researches about the vibration reduction of grass trimmer vibration [7,8].…”

Numerous epidemiological studies have shown that operators who use hand-held power tools are prone to develop hand-arm vibration syndrome. Therefore, it is necessary to reduce the tool vibrations to protect the worker's health. This research focuses on the dynamic modeling and the vibration simulation of orbital sanders which are commonly used in industrial sectors. The mathematic model with eighteen degrees-of-freedom (DOF) of this machine is established based upon the Lagrange equation. The experiments are also conducted to test vibrations at the top of the housing where the operators hold the machine. The simulated results are found in good coincidence with the experimental results, and the errors between the experimental results and the simulated values are in acceptable range, which demonstrates the mathematic model in this paper is accurate.
