The Third Edition includes two chapters which offer a review of feedback control systems and an overview of digital control. eEdition-2 of the Third Edition is the same as eEdition-1, except the composition has been compressed in order to improve the quality of the typesetting, save pages, and reduce the memory storage required, and the Table of Contents and the Index have been revised to reflect the new pagination.
MATLAB is thoroughly integrated into the text, in exposition and in problems, to offer readers a complete design picture. The e-Edition-2 of the Third Edition has been updated to be fully compatible with current MATLAB versions as of 2022 and includes twice as many end-of-chapter problems as the previous, printed, Second Edition.
This 2022 PDF e-Edition-2 supersedes all prior printings of the Third Edition of Digital Control of Dynamic Systems, and includes updates to key items and corrections for all known errors found in previous printings.
There is a Summary at the end of each chapter and Problems for the students to work out. There are also Appendices that review basic material, contain a table of z-transforms, and a list of pertinent MATLAB Functions.
A transfer function model describes an input-output relationship of a system using a ratio of polynomials. So, an input signal is given to a system to produce a controlled output (aka response). This type of modeling is different than using differential equations and state-space representations where the model dynamics is available.
The transfer function of a control system is the ratio of the Laplace transforms (\mathscrL\\) of output signals over the Laplace transform of the input signal. In a nutshell, instead of analyzing a model in the time-domain using time-based differential equations, the goal here is to analyze the model in the frequency-domain using a transformation.
In this post, we are only interested in the initial response of the system in order to answer the question of why the shower first gets cold before it gets hot? Since the initial system response is closely related to system zeros as noted earlier, therefore, we will not talk about the poles (perhaps that can be a topic for another article).
Note that there is only one minimum phase system for a given magnitude response, but there is an infinite number of NMP systems. This is the reason why we do not hear a term like the maximum phase system. See [3] for more detail about non-minimum phase systems with mathematical description.
The negative derivative of u(t) in System 2 causes the step response of System 2 to go first towards the opposite direction of the expected response (steady-state value) before moving towards the expected response (the red curve). This is in contrast to the step response of System 1 (blue curve) that does not have this undershoot at the beginning. For a nice illustration of what non-minimum phase systems are, you can check [4].
In this article, we learned about what a non-minimum phase system is and why such a system first experiences response in the wrong direction (you turn the hot water knob, and the water is first cold!). We also talked about the transfer function and how it can be useful in analyzing systems.
