If you define a state-space model implicitly and the response and predictor data (i.e., y and Z) exist in the MATLAB® Workspace, then the software creates a link from the parameter-to-matrix mapping function those series. If the data do not exist in the MATLAB Workspace, then the ...
State space modelSmall-signal stability analysisAVRFuzzy logic controllerThis paper presents a linear mathematical model of a Synchronous Generator with excitation system for small signal stability analysis. This work aims to develop a controller based on fuzzy logic to simulate an Automatic Voltage ...
To predict the lateral equations of the H4 Hercules using a greybox model, I defined the model function as follows and set the initial values for the parameters before executing it. (Since I am estimating a linear model, I extracted the data from the trim state, so the...
In recent years, there has been a growing interest in incorporating fractional calculus into stochastic delay systems due to its ability to model complex phenomena with uncertainties and memory effects. The fractional stochastic delay differential equati
Thus, polymerization and depolymerization were balanced and a steady state with constant average polymer length was reached. In contrast, at high motor particle density, which caused a high rescue frequency, complete depolymerization could be observed only at initial stages of the simulation. In this...
The slope stability analysis can not only provide basis for economical and reasonable slope design, but also help to make judgments about the stability state and evolution trend of no matter artificial or natural slopes, prevent the potential risks and guide the slope treatment. Due to the economi...
In this paper, we investigate a class of linear parameter-varying discrete time-delay (LPVDTD) systems where the state-space matrices depend on time-varying parameters and the delay is unknown but bounded. We treat both notions of quadratic stability based on a single quadratic Lyapunov function...
By defining virtual state and measurement output vectors as and respectively, and using (31)–(33), the closed-loop LFC system can be expressed as follows: (34)where with the parameters given in [35]: and . Based on the discussion of Section 3.2 and the similar procedure of [35], the...
A critical component of this study is how dissipation, revealed in a system’s phase space behavior, is manifested on and near the attractor and how it can be revealed using only time series data of the state variables. In this way, we are not assuming a priori that stability is only re...
Small-signal Stability Characterization of Interaction Phenomena between HVDC System and Wind Farms Small-signal stability analysis in the frequency domain based on the state-space modeling and eigenvalue analysis, and the impedance-based analysis are carried out for the VSC-based HVDC transmission syste...
