Digital Controllers

When an application needs a close loop, CEDRAT TECHNOLOGIES offers different solutions built around digital controllers with more or less versatility and capability.

CEDRAT TECHNOLOGIES has developed software HDPM downloadable on the GUI webpageHDPM is our graphic user interface. HDPM allows to set the control laws. (Proportional Integral Derivate parameters + Additional filters selected among standard low pass or stop band filters with orders up to 4).

Description
The UC55 board has the same format than the UC45, but it features a higher control rate and it exists in three different versions: single channel, dual channel, and triple channel. In single channel, the control rate is 30kSps, in dual channels, 15kSps, and in triple channels, 10kSps. The UC55 boards can also be stacked to handle several independent control channels at high frequency (up to 3).
Performances
Sampling frequency: 10/15/30 kSps; Computer Interface: USB type B
