MB Millenium Dynamic Test Control System

Multi-Input, Multi-Output (MIMO) and Multi-Input, Single-Output (MISO)

The MB Millenium™ from MB Dynamics is a multiple-input, multiple-output (MIMO) and/or a multiple-input, single-output (MISO) dynamic test control system.

MB Dynamics Millenium Single and Multi Axis Dynamic Control System

It reliably and accurately replicates actual end-user test conditions, including force, acceleration and motion control parameters, and can be used to control up to eight actuators, simultaneously or sequentially. The actuators are connected to a single test article that can be running independent force and/or vibration and motion profiles, whether synchronized or unsynchronized. Typical applications include time history replication, random vibration (PSD) control, and single- and multi-shaker sine with user-defined frequency and phase relationships.

The associated features and functionality of the MB Millenium dynamic test control system are borne from the company’s more than 80 years of know-how in vibration, shock and dynamic testing, both in-lab and in-field. System performance is further enhanced by the integration of commercially available, continuously evolving A/D and D/A hardware, with full engineering support available from National Instruments (NI), one of the industry’s most experienced teams.

MB Dynamics Millenium Single and Multi Axis Vibration and Motion Control System The Eagle is the current platform in the MB Millenium family. It performs vibration control (acceleration and displacement), static and dynamic force control, linear and rotary motion control, and static and dynamic pneumatic control of test actuators and test functions. Each Eagle has one or more embedded controllers performing control functions, with analog and digital I/O provided by a variety of NI data acquisition and DIO boards. It uses either a customer- or MB-supplied Windows 10 desktop or tower PC for its graphical and user interface. The Windows 10 host is completely removed from all control processes running on the Eagle. As it operates as a non-networked, stand-alone unit, operation of the Eagle is therefore unaffected by Windows updates, IT security programs or corporate software.

The MB Millenium MIMO software is a natural continuation of the innovative, real-time signal processing work commenced by MB in the 1980’s, which includes under-constrained, noisy (non-Gaussian noise) multi-degree of freedom (DoF) dynamic systems. The proprietary techniques and algorithms incorporated into the MIMO implementation include impulse-response conditioning, time-domain feedback, and predictive noise-quelling. MIMO incorporates classic algorithms along with novel treatments. Its advanced software product development demonstrates the MB commitment to continuous improvements across its full family of vibration, force, and motion control products.
