  2. State-space representation - Wikipedia

    en.wikipedia.org/wiki/State-space_representation

    In control engineering and system identification, a state-space representation is a mathematical model of a physical system that uses state variables to track how inputs shape system behavior over time through first-order differential equations or difference equations. These state variables change based on their current values and inputs, while ...

  3. File:Typical State Space model.svg - Wikipedia

    en.wikipedia.org/wiki/File:Typical_State_Space...

    English: Block diagram showing how the matrices of the state space representation are combined to give the state and output vectors from the input. Date December 2004

  4. State observer - Wikipedia

    en.wikipedia.org/wiki/State_observer

    Block diagram of Luenberger Observer. Input of observer gain L is y − y ^ {\displaystyle y\mathbf {-} {\hat {y}}} . Linear, delayed, sliding mode, high gain, Tau, homogeneity-based, extended and cubic observers are among several observer structures used for state estimation of linear and nonlinear systems.

    English: Block diagram showing how the matrices of the state space representation are combined to give the state and output vectors when a feedback is performed. Date December 2004

  6. Control theory - Wikipedia

    en.wikipedia.org/wiki/Control_theory

    In contrast to the frequency domain analysis of the classical control theory, modern control theory utilizes the time-domain state space representation, [citation needed] a mathematical model of a physical system as a set of input, output and state variables related by first-order differential equations. To abstract from the number of inputs ...

  7. Bloch sphere - Wikipedia

    en.wikipedia.org/wiki/Bloch_sphere

    In quantum mechanics and computing, the Bloch sphere is a geometrical representation of the pure state space of a two-level quantum mechanical system , named after the physicist Felix Bloch. [ 1 ] Mathematically each quantum mechanical system is associated with a separable complex Hilbert space H {\displaystyle H} .

  8. Bond graph - Wikipedia

    en.wikipedia.org/wiki/Bond_graph

    It allows the conversion of the system into a state-space representation. It is similar to a block diagram or signal-flow graph, with the major difference that the arcs in bond graphs represent bi-directional exchange of physical energy, while those in block diagrams and signal-flow graphs represent uni-directional flow of information. Bond ...

  9. Closed-loop pole - Wikipedia

    en.wikipedia.org/wiki/Closed-loop_pole

    The open-loop transfer function is equal to the product of all transfer function blocks in the forward path in the block diagram. The closed-loop transfer function is obtained by dividing the open-loop transfer function by the sum of one and the product of all transfer function blocks throughout the negative feedback loop. The closed-loop ...
