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.

Universal Robots - Collaborative Robot Solutions

Universal Robots is a result of many years of intensive research in robotics. The product portfolio includes the UR5 and UR10 models that handle payloads of up to 11.3 lbs. and 22.6 lbs. respectively. The six-axis robot arms weigh as little as 40 lbs. with reach capabilities of up to 51 inches. Repeatability of +/- .004" allows quick precision handling of even microscopically small parts. After initial risk assessment, the collaborative Universal Robots can operate alongside human operators without cumbersome and expensive safety guarding. This makes it simple and easy to move the light-weight robot around the production, addressing the needs of agile manufacturing even within small- and medium sized companies regarding automation as costly and complex. If the robots come into contact with an employee, the built-in force control limits the forces at contact, adhering to the current safety requirements on force and torque limitations. Intuitively programmed by non-technical users, the robot arms go from box to operation in less than an hour, and typically pay for themselves within 195 days. Since the first UR robot entered the market in 2009, the company has seen substantial growth with the robotic arms now being sold in more than 50 countries worldwide.
