Why
adopt multivariable
control?
Adopting multivariable
control strategy is greatly expanding the
frequency control range, VibExpert control
software for VENZO vibration controller can
realize continuous sine sweep test from 0.01Hz to
25600Hz, the dynamic range of controllable sine
acceleration signal is up to 150dB. Especially for
hydraulic shaker, join with the displacement
control channel, greatly improving the low
frequency control precision, effectively avoiding
the runaway phenomenon under the traditional
acceleration control, such as hydro-cylinder
collision, over displacement and so on. By the
way, waveform distortion is also effectively
suppressed with multivariable control
strategy.
