| Summary: | Control of vibration suppressions is crucial
for applications in engineering particularly in the area of
aircraft system. A hybrid control approach encompasses
of using a feedforward intelligent command shaping
technique with combination of intelligent PID feedback
control is presented in this paper. The advantage of
using command shaping is to reduce system vibration.
However, it can cause delay in system response resulting
to a conflict between vibration suppression and rise time
response. Multi objective genetic algorithm is employ in
this work to determine a set of solutions for the
amplitudes and corresponding time locations of impulses
on an extra sensitive (EI) command shaping as well as
gain parameters for the PID controller. The effectiveness
of the proposed technique is assessed both in the time
domain and the frequency domain. Moreover, a
comparative assessment of the performance of the
technique with the system response and unshaped finite
step input is presented. |
