Discrete state-space system

Block Screenshot

Description

This block realizes a discrete-time linear state-space system. The system is defined by the matrices and the initial state . The dimensions must be compatible. At the arrival of an input event on the unique input event port, the state is updated.

Dialog box

  • A matrix

    square matrix.

    Properties : Type 'mat' of size [-1,-1].

  • B matrix

    The matrix, [] if system has no input.

    Properties : Type 'mat' of size ["size(%1,2)","-1"].

  • C matrix

    The matrix, [] if system has no output.

    Properties : Type 'mat' of size ["-1","size(%1,2)"].

  • D matrix

    The matrix, [] if system has no D term.

    Properties : Type 'mat' of size [-1,-1].

  • Initial state

    A vector/scalar initial state of the system.

    Properties : Type 'vec' of size "size(%1,2)".

Default properties

  • always active: no

  • direct-feedthrough: no

  • zero-crossing: no

  • mode: no

  • regular inputs:

    - port 1 : size [1,1] / type 1

  • regular outputs:

    - port 1 : size [1,1] / type 1

  • number/sizes of activation inputs: 1

  • number/sizes of activation outputs: 0

  • continuous-time state: no

  • discrete-time state: yes

  • object discrete-time state: no

  • name of computational function: dsslti4

Interfacing function

  • SCI/modules/scicos_blocks/macros/Linear/DLSS.sci

Computational function

  • SCI/modules/scicos_blocks/src/c/dsslti4.c (Type 4)
