Feedback is extensively used in control theory, using a variety of methods including state space (controls), full state feedback, and so forth. Note that in the context of control theory, "feedback" is traditionally assumed to specify "negative feedback". The most common general-purpose controller using a control-loop feedback mechanism is a proportional-integral-derivative (PID) controller. Heuristically, the terms of a PID controller can be interpreted as corresponding to time: the... See More
PES Pareto is a method to categorize the strata of broadband noise in the frequency domain for a feedback (or feedforward) system. The idea is to isolate noise measurements and then back filter their Power Spectral Densities (PSDs) through the appropriate magnitude squared filter to be able to model the noise as an independent noise input. All of the various isolated independent noise inputs can then have their PSDs forward filtered through the appropriate magnitude squared filter to show their... See More
Control education deals with how controls engineers, control researchers, and educations teach topics in the field of automatic control. There is often some confusion because these different groups will often visualize different audiences for the topic. For our broad definition here we can consider the following audiences: Future controls researchers: This crowd has taken their first automatic control class in college or graduate school and has loved it so much that they wish to pursue it in...
