Dataset collected using a control strategy on a triaxial platform

The aim was to assess how different acceleration-control strategies influence the dynamic response of the platform and cross-axis effects. Four closed-loop strategies were investigated: (1) single-point control using one triaxial accelerometer, (2) control using three single-axis accelerometers, one per axis, (3) distributed control using three triaxial accelerometers, and (4) multi-point response with rectangular control through three accelerometers.

Acceleration measurements were collected during sweep-sine and random vibration tests over the 5-2000 Hz frequency range. All data were acquired on the LMN triaxial vibration test bench, which enables coupled or uncoupled excitation along three orthogonal axes. Signal generation, closed-loop control, and data acquisition were performed using Spectral Dynamics Jaguar hardware and software.
