As modern products become larger, lighter, and more structurally sophisticated, traditional single-input vibration testing can no longer accurately reproduce real-world operating environments. Aircraft structures, electric vehicles, satellite components, railway equipment, and large assemblies are all subjected to forces from multiple directions simultaneously.

To simulate these complex environments, engineers require a controller capable of coordinating multiple shakers with exceptional synchronization, stability, and control accuracy.

The MIMO Vibration Controller is specifically engineered for these demanding applications. Powered by distributed multi-DSP architecture and over two decades of vibration control expertise, it enables accurate, repeatable Multiple-Input Multiple-Output (MIMO) testing for both electrodynamic and electro-hydraulic vibration systems.

Built for Complex Multi-Axis Testing

• Supports up to 16 independent drive channels
• Accommodates up to 64 synchronized input channels per controller
• Controls multiple shakers simultaneously for coordinated vibration simulation
• Suitable for multi-axis, multi-exciter, and large-scale structural testing

Whether validating an aircraft structure, a vehicle body, or a large engineering assembly, the controller accurately reproduces complex vibration environments that cannot be achieved with conventional single-axis control.

Advanced Control Algorithms for Higher Accuracy

• Adaptive matrix control continuously optimizes system performance
• Matrix decoupling minimizes interaction between multiple shakers
• Diagonal-first matrix compensation improves control stability
• Partial coherence technology enhances correlation between control points
• Complex heterodyne algorithms improve response accuracy

These advanced control technologies help engineers obtain more realistic and repeatable test results while reducing control errors in highly coupled systems.

Designed for Reliable Long-Term Operation

• Distributed multi-DSP parallel processing architecture
• Modular hardware design for flexible system configuration
• PXI bus architecture over Ethernet provides reliable communication
• Supports hot reconnection without interrupting testing or losing data

The robust architecture ensures stable operation during long-duration and high-channel-count testing programs.

Comprehensive Safety Protection

• Open-loop detection for abnormal operating conditions
• RMS cutoff protection
• Drive limit monitoring
• Control limit line protection
• Emergency stop and shaker protection functions

Multiple layers of protection safeguard both valuable test specimens and vibration equipment throughout the testing process.

Simple Operation, Powerful Capability

• Windows-based graphical user interface
• No dedicated interface card or proprietary driver installation required
• Easily connects through standard Ethernet
• Automatically generates professional test reports after completion

By simplifying setup and reporting, engineers can spend less time configuring equipment and more time analyzing test results.
