This two-day, interactive seminar explores modeling, analysis, characteristics and design of analog control systems for electrohydraulic applications. Electronic control systems are becoming the cornerstone of technological advancement. A review of modeling and analysis methods will allow participants to move into a detailed examination of proportional-integral-derivative (PID) controllers as well as phase-lag and phase-lead controllers. Electrohydraulics valve characteristics, position control and velocity control will be examined in applying control methods to fluid power systems.
Who Should Attend?
Applications engineers, systems integrators, electrohydraulic motion control engineers, product development engineers and the end users of control systems will find this seminar invaluable.
