Variable Stability Transfer Function Simulation
… and gains. The simulation was obtained using transfer functions representing the aircraft state responses to control inputs. These transfer functions were converted into state space systems used to create the linear equations for the model. The model was first developed as a desktop simulation …

Damping optimization using transfer function criteria
Seismic performance has become a key point in the design of every type of structures. Even the simplest buildings need protection in areas of high seismic activity.However,there is no method defined!by codes or general knowledge to help engineers make choices about the design of seismic protection …

Transfer function estimation using time-frequency analysis
Given limited and noisy data, identifying the transfer function of a complex aerospace system may prove difficult. In order to obtain a clean transfer function estimate despite noisy data, a time-frequency analysis approach to system identification has been developed. The method is based on the …

Analysis of Multivariate Stochastic Hydrological Systems Using Transfer Function-Noise Models
In recent years, hydrologists have attempted, with encouraging results, to synthesize the accomplishments of univariate time series analysis and deterministic systems methods into the more general framework of stochastic dynamic systems. Nevertheless, many problems remain unsolved, others still …

Generalized modelling of a space station and determination of the transfer function
… a generalized method for deriving a theoretical transfer function between astronaut force inputs and station acceleration outputs is postulated. The validity of this transfer function can then be examined using the experimental force and acceleration data collected from Mir from the period of …

Portable sensor to measure the mechanical compliance transfer function of a material
… creates a non-parameterized impulse response function in addition to a fit second order model for the material. The device was tested on a compliant sponge sample which exhibited highly nonlinear dynamic behavior. The low frequency compliance of the sponge was measured with the device with 16% …

Passive Rational Fitting of a Passive Network Transfer Function From Its Real Part
A methodology is presented to generate a rational function approximation of a passive network transfer function that makes use of sampled values of the transfer function's real part at a set of frequencies over the bandwidth of interest. For passive networks, real-part sufficiency describes the …

Characterization of the head-related transfer function using chirp and maximum length sequence excitation signals
… used to obtain measurements of the head-related transfer function (HRTF) for the Knowles electronic manikin for acoustic research (KEMAR), resulting in remarkably low relative error between the two measurement methods. Due to the low relative error, it is asserted that applying both methods in …

Investigation of Lateral-Directional Coupling in the Longitudinal Responses of a Transfer Function Simulation Model
The linear variable stability Transfer Function Simulation Model (TFSM), inspired by the United States Air Force's NF-16D Variable stability In-flight Simulator Test Aircraft (VISTA) and created by Henrik Pettersson, can simulate any desired aircraft. The TFSM represents a non-linear aircraft model …

Near aggregation: a time and frequency domain analysis using state trajectories and transfer function residues
… we then obtain an upper bound on the norm of the transfer function residue using near-unobservability measures. The Generalized Hessenberg Representation (GHR) and Dual GHR are examined throughout this analysis. It is finally shown that for SISO systems, the residue norm may be expressed in terms …
