Interactive Lab Assistant: Closed-loop control of a 4-quadrant drive system

Experiment instructions take the form of an Interactive Lab Assistant course. This multimedia course guides students step by step through the topic "Closed-loop control of a 4-quadrant drive system". Physical principles are conveyed by means of easily understood animations. Along with virtual instruments, the Interactive Lab Assistant presents a comfortable environment for your experiments.

Features:

• Interactive set-up instructions for experiments
• Measurements and graphics can be copied to the instruction pages by means of “drag and drop”.
• Virtual instruments can be run directly from the instruction pages
• Questions with feedback and assessment logic for testing students’ knowledge
• Printable document so that you can easily print out experiment instructions along with solutions
• Labsoft browser, course software and virtual instruments
• Course duration: 10 h approx.

Training contents:

• Distinction between open-loop and closed-loop speed control
• Design and optimisation of a closed-loop drive control system using all four quadrants
• Identification of control loop
• Determination of suitable control parameters in time and frequency domains using similar methods to those utilised in practice (Kuhn, Latzel, Ziegler-Nichols, Bode plots)
• Effect of controller components on the results of the control loop
• Design and optimisation of cascade control for control of current and speed
