ZEN Active Control System
A wideband 3 Channels X-LMS
A powerful, easy-to-use, compact and low cost controller
Figure 1 Schematic of the 3-Channel ZEN Active Control System
Main Features
6 inputs (3 reference signals, 3 error signals) and 3 outputs for the control signals
Real-time X-LMS feed-forward with filtered references and a LMS optimization
Wideband control up to 36 kHz on 3 channels simultaneously
Interaction between each channels take into account (coupled mode) or not (non-coupled mode)
Up to 30 dB of noise reduction (wideband applications) and up to 60 dB of noise reduction (narrow-band
applications)

A friendly PC user interface which allows to adjust the algorithm parameters and to analyze the control results
Applications Fields
The ZEN Active Control System is ideal for acoustic and vibration application.

In most real applications, the attenuation is limited by other parameters than the controller (precision or/and dynamic range of the sensors, power
and/or linearity of the actuators).
