Abstract
Currently, the dependency on the use of handheld power tools such as jack hammer and
pneumatic grinder among the industry workers are substantially high due to its wide
functionality and great efficiency which make the performed tasks become easier.
Nevertheless, these tools are subjected to the undesirable vibration during operation which may
cause adverse effects to workers’ health after a long exposure such as the development of
HAVs. In the published literature, there are very limited simulation studies on vibration
attenuation of suspended handle using an inertia-type piezoelectric actuator, whereby a wide
range of parametric study can be done to investigate the performance of the piezoelectric
actuator. Therefore, this research will investigate different parameters of an inertia-type
piezoelectric actuator in reducing the vibration of suspended handle model using simulation in
MATLAB and Simulink software. From the result, AVC system with ZN tuning method is the
most effective in reducing the vibration of suspended handle compared to PID (auto and
manual) and passive system. Among the tuning parameters, ZN method with the tuned
parameter of 10 times higher than original value has the best performance with 99.96%
vibration attenuation of suspended handle. As a conclusion, the AVC system with ZN tuning
method is a promising solution for the vibration control, particularly in the application of power
tools.
