Webinar recording — Digital feedback control loops in the frequency domain
Overview
In this webinar, we introduce the essentials of feedback control loops as described in the frequency domain. Beginning from the fundamental ideas of transfer function and frequency response, learn how to construct complex systems from basic building blocks. Then see how to analyze their performance in terms of reference tracking and disturbance rejection, while focusing on loop stability.
To conclude the discussion, we use reconfigurable, FPGA-based instrumentation to demonstrate a feedback control loop. Watch on demand to see how the all-digital, software-defined framework enables swift parameter changes with integrated characterization and measurement tools that ensure design goals can be quickly achieved.
A live Q&A session follows the presentation. For detailed answers to questions asked during the presentation, including decoding digital feedback signals, improving loop stability, and how Nyquist sampling affects the Moku PID Controller feedback bandwidth, check out our blog.
What we covered:
- Learn about the theory of control loops in the frequency domain.
- Find out how the FPGA-based Moku PID Controller can offer a complete, closed-loop control system in one device.
- See how a digital control loop can speed up iteration compared to analog circuits.
The webinar includes a presentation, demonstration, and live Q&A session.
