​VT-8 Series MIMO Vibration Controller is one of the kernel parts in multi-shaker or multi-axis vibration testing system. It builds multiple control loops among multiple shakers and multiple DOF with matrix control algorithms, amplitude and phase.
VT-8 series is designed based on PXI bus and self-contained controller, supporting independent running without PC. Its inputs and drives are modular and expandable with high synchronization precision. VT-8 series support software including MIMO Random, MIMO Sine, MIMO Shock and MIMO Field Data Replication in time domain, with precise system identification, multiple adaptive loop control, sophisticated coupling and decoupling matrix algorithms for amplitude and phase.
VT-8 series has been successfully put into many actual MIMO vibration test cases, such as 2 or 4 posts vehicle test, transportation and road simulation, flying objects and aerodynamic test, etc.
VT-8 series also could be used for single shaker vibration control, high channel account measurement and structural modal analysis.
