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).
