Galil Introduces Frequency Analysis Software – Allows Tuning in the Frequency Domain

Galil Motion Control, an industry pioneer in motion control technology, is announcing Frequency Analysis Software (FAS) which allows tuning of servo control systems in the frequency domain.

Rocklin, CA — Galil Motion Control, an industry pioneer in motion control technology, is announcing Frequency Analysis Software (FAS) which allows tuning of servo control systems in the frequency domain. Tuning in the frequency domain is often preferred for systems with resonances or when the design engineer is comfortable with classroom control theory.


"While in most cases tuning servo systems in the time domain works well (Galil's GalilTools software provides tuning in the time domain), Galil's new Frequency Analysis Software provides an alternative option for tuning systems," said Lisa Wade, Vice President of Sales and Marketing. "It is especially useful for tuning systems with resonances."

The new software in conjunction with a Galil motion controller measures the frequency response of the plant to be controlled. It simulates the possible control solutions and synthesizes the two to allow for Bode analysis of the closed loop system.

FAS plots the magnitude versus frequency and phase versus frequency for both the Galil motion controller and the plant. The plant's frequency response is measured from the actual plant. The controller's response is simulated based on the selected control parameters. The product of the two functions is the system open loop frequency response.

The Frequency Analysis Software allows the designer to try various simulations of the controller parameters such as the PID filter and notch parameters and combine them with the plant to give the open loop frequency response. Based on the simulations, the designer can determine the best controller parameters to meet the desired performance criteria of phase margin and cross-over frequency for his system.

FAS software is available for Galil's DMC-41x3 Econo and DMC-40x0 Accelera motion controllers. The U.S. list price is $195, and it is available for immediate shipment.

BitFlow Introduces 6th Generation Camera Link Frame Grabber: The Axion

BitFlow has offered a Camera Link frame grabbers for almost 15 years. This latest offering, our 6th generation combines the power of CoaXPress with the requirements of Camera Link 2.0. Enabling a single or two camera system to operate at up to 850 MB/S per camera, the Axion-CL family is the best choice for CL frame grabber. Like the Cyton-CXP frame grabber, the Axion-CL leverages features such as the new StreamSync system, a highly optimized DMA engine, and expanded I/O capabilities that provide unprecedented flexibility in routing. There are two options available; Axion 1xE & Axion 2xE. The Axion 1xE is compatible with one base, medium, full or 80-bit camera offering PoCL, Power over Camera Link, on both connectors. The Axion 2xE is compatible with two base, medium, full or 80-bit cameras offering PoCL on both connectors for both cameras. The Axion-CL is a culmination of the continuous improvements and updates BitFlow has made to Camera Link frame grabbers.
