Control Strategies for Dynamic Systems: Digital and Mechatronics

This applications-oriented seminar explores the characteristics of analog and digital controllers, sensors and advanced controls topics such as adaptive, nonlinear, fuzzy and multivariable controllers. Time will be spent discussing the implementation of digital controllers including computer interfacing and microprocessors. As electrohydraulics moves toward autonomous systems, controls of all components as well as prognostics and control integration of systems are becoming critical issues in continued technological advancement.

Who Should Attend?

Applications engineers, systems integrators, electrohydraulic motion control engineers, product development engineers and the end users of fluid power systems will find the seminar invaluable. Participants are encouraged to attend "Basic Control Strategies for Fluid Power Applications" prior to attending this seminar.

Seminar Objectives

Upon completion, participants should be able to do the following:
  • Apply principles of digital and analog controllers in designing integrated systems
  • Analyze and understand the differences in sensors for controls applications
  • Implement digital controllers and evaluate step responses, steady-state errors and tuning methods
  • Understand multivariable, system identification, adaptive, nonlinear and fuzzy controls
