Discrete State Space

Purpose

Implement discrete time-invariant system as state-space model

Library

Control / Discrete

Description

pict

The Discrete State Space block models a state space system of the form
xi+1 = Axi + Bui,yi = Cxi + Dui  , where xi   is the state vector at sample time step i  , u   is the input vector, and y   is the output vector.

Parameters

A,B,C,D
The coefficient matrices for the discrete state space system. The dimensions for the coefficient matrices must conform to the dimensions shown in the diagram below:

where n   is the number of states, m   is the width of the input signal and p   is the width of the output signal.

Sample time
The time interval between samples. See also the Discrete-Periodic sample time type in section Sample Times.
Initial condition
A vector of initial values for the state vector, x  .

Probe Signals

Input
The input vector, u  .
Output
The output vector, y  .
