  2. Transfer function - Wikipedia

    en.wikipedia.org/wiki/Transfer_function

    Transfer function. In engineering, a transfer function (also known as system function[1] or network function) of a system, sub-system, or component is a mathematical function that models the system's output for each possible input. [2][3][4] It is widely used in electronic engineering tools like circuit simulators and control systems.

  3. Nyquist stability criterion - Wikipedia

    en.wikipedia.org/wiki/Nyquist_stability_criterion

    The Nyquist stability criterion is a graphical technique that determines the stability of a dynamical system, such as a feedback control system. It is based on the argument principle and the Nyquist plot of the open-loop transfer function of the system. It can be applied to systems that are not defined by rational functions, such as systems ...

  4. Impulse response - Wikipedia

    en.wikipedia.org/wiki/Impulse_response

    The impulse response of a linear transformation is the image of Dirac's delta function under the transformation, analogous to the fundamental solution of a partial differential operator. It is usually easier to analyze systems using transfer functions as opposed to impulse responses. The transfer function is the Laplace transform of the impulse ...

  5. Control theory - Wikipedia

    en.wikipedia.org/wiki/Control_theory

    Frequency domain – In this type the values of the state variables, the mathematical variables representing the system's input, output and feedback are represented as functions of frequency. The input signal and the system's transfer function are converted from time functions to functions of frequency by a transform such as the Fourier ...

  6. Stability theory - Wikipedia

    en.wikipedia.org/wiki/Stability_theory

    Stability generally increases to the left of the diagram. [1] Some sink, source or node are equilibrium points. In mathematics, stability theory addresses the stability of solutions of differential equations and of trajectories of dynamical systems under small perturbations of initial conditions. The heat equation, for example, is a stable ...

  7. Binary decision diagram - Wikipedia

    en.wikipedia.org/wiki/Binary_decision_diagram

    Binary decision diagram. In computer science, a binary decision diagram (BDD) or branching program is a data structure that is used to represent a Boolean function. On a more abstract level, BDDs can be considered as a compressed representation of sets or relations. Unlike other compressed representations, operations are performed directly on ...

  8. Function model - Wikipedia

    en.wikipedia.org/wiki/Function_model

    A function model, similar with the activity model or process model, is a graphical representation of an enterprise's function within a defined scope. The purposes of the function model are to describe the functions and processes, assist with discovery of information needs, help identify opportunities, and establish a basis for determining ...

  9. Linear system - Wikipedia

    en.wikipedia.org/wiki/Linear_system

    Linear system. In systems theory, a linear system is a mathematical model of a system based on the use of a linear operator. Linear systems typically exhibit features and properties that are much simpler than the nonlinear case. As a mathematical abstraction or idealization, linear systems find important applications in automatic control theory ...
