How to Tune Servo Systems: Tuning for Optimal Performance

Tuning_Banner__1_

About the Webinar

Among the most troubling tasks in machine building can be tuning the servo system to meet or exceed the performance specification. Invariably, we have all sat at the machine and asked ourselves, “What three numbers should I put in this proportional-integrated-derivative (PID) controller?” However, when tuning, it is not always about the PID gains. Many other factors affect the tuning and can be changed to improve machine performance. This webinar series will discuss aspects of controller design, including control loop structures and using frequency-based tools for gain selection, filter selection and machine characterization.

Presenter Joseph Profeta, who has nearly three decades of experience working on challenging automation solutions for a variety of industries, will explain the steps he takes to optimize the performance of motion systems.

Part Two – Tuning Servo Systems for Optimal Performance

Part Two will cover more advanced frequency domain usage, including different frequency responses (sensitivity, inverse feedforward and process sensitivity) and dealing with non-linearity, such as small signal analysis and friction.

Learning Objectives

  • Briefly review the basics of a frequency response
  • Understand loop shaping by considering various frequency responses including loop transmission, plant, inverse feedforward, sensitivity and process sensitivity responses
  • Explore the effects that non-linearities, such as friction, low vs high current, and load variation, have on system performance

He will teach attendees how to tune a servo system using frequency-based tools to optimize system performance. This includes setting the optimal feedforward gains, setting parameters and filter placement to achieve robustness.

Who Should Attend

Engineers and researchers who design and build automation equipment with servo technology to achieve medium- and high-performance control of position, velocity and/or force would benefit from attending. The webinar would be helpful to those involved in a wide range of automation applications from laser processing, semi-conductor inspection, die bonding, winding applications, and labelling systems.
