Three-dimensional visualization of Nichols, Hall, and robust-performance diagrams
Kent H. Lundberg, Zachary J. Malchano · 2004
Three-dimensional models and animations of Nichols charts, Hall charts, and robust-performance diagrams are presented. Using these models, students can visualize the implications and importance of these charts and diagrams. By viewing these animations, students develop better intuition concerning the connection between open-loop gain/phase plots, open-loop polar plots, and closed-loop frequency response.
