Example – Fundamentals of Linear Control: A Concise Approach

Step-by-step Nyquist plot example. Part III

One more on Nyquist plots this time for a non-minimum-phase transfer-function with a pole at the origin.

Step-by-step Nyquist plot example. Part II

Second part of our posts on the Nyquist plot. This time with a non-minimum-phase transfer-function.

Step-by-step Nyquist plot example. Part I

We went over how to sketch straight-line approximations in Bode plots in a series of posts. In this post we continue those examples by going from the Bode plot to a Nyquist plot.

Step-by-step Bode plot example. Part IV

We continue our saga of hand sketches of the straight-line approximations for the magnitude and phase of Bode plot diagrams (Section 7.1). This time we consider a non-minimum phase system with a pole at the origin. See Part I, Part II and Part III, for simpler examples.

Step-by-step Bode plot example. Part III

We have gone step-by-step over how to sketch straight-line approximations for the magnitude and phase diagrams of the Bode plot for a simple rational transfer-function. This transfer-function had only left-hand side poles and zeros, that is it was minimum-phase (see Section 7.2). In this post we consider a non-minimum phase transfer-function with a right-hand side zero. See Section 7.1 for details on the approximations.

Step-by-step Bode plot example. Part II

In a previous post we have gone step-by-step over how to sketch straight-line approximations for the magnitude diagram of the Bode plot for a simple rational transfer-function. In this post we cover the sketch of the phase diagram. See Section 7.1 for details on the approximations.

Step-by-step Bode plot example. Part I

In this post we will go over the process of sketching the straight-line Bode plot approximations for a simple rational transfer-function in a step-by-step fashion. See Section 7.1 for details on the approximations. We will start with the magnitude plot and cover the phase plot in a future post.
