Introduction To Frequency Response Methods
1968The concept of frequency response testing has previously been considered in relation to the second-order servomechanism (ยง8.9). In these considerations the connections between transient and frequency response have been introduced. For higher order systems frequency response methods are extremely valuable for a number of reasons some of which are ...

Open-loop frequency response method
Electrical Engineering, 1953SERVOMECHANISM DESIGN and test procedures which are based upon the assumption of system linearity are not satisfactory for many servos. This problem has been summarized in a recent article in this magazine.1 A method for representing the open-loop frequency response of nonlinear systems will be considered which indicates the presence of most nonlinear ...

Approximation of frequency responses based on Larsson's method
Structural Optimization, 1994This paper discusses the new aspects of the formulation for structural model updates presented by Larsson and Sas at the 10th International Modal Analysis Conference held in San Diego, California in February 1991. First, a closed-form representation of the reduced impedance matrix is presented.

Improved MATLAB GUIs for Learning Frequency Response Methods
IFAC Proceedings Volumes, 2013The author developed two GUIs for asymptotic Bode plots and identification from such plots aimed at improving the learning of frequency response methods: these were presented at UKACC Control 2012. Student feedback and reflection by the author suggested various improvements to these GUIs, which have now been implemented.

An approximate method for obtaining transient response from frequency response
Proceedings of the IEE - Part B: Radio and Electronic Engineering, 1955A number of approximate methods are known for obtaining the transient response of a linear system from its frequency response when the latter is known numerically but not as an analytical function. The paper presents a new method for performing this transformation which is believed to be considerably quicker and more convenient than previous methods ...

A Method for Deriving Frequency Response from Transient Response Data
1960Abstract : The characteristics of a linear component are known to be completely determined by its steady state frequency response which relates the output of the component to its input. Hence, the analysis and synthesis of a complex system are simplified when the frequency response of each unit making up the system is known.
