Description

This block realizes a continuous-time linear state-space system.

$$\begin{eqnarray} \dot x&=Ax+Bu\\ y &=C*x+D*u \end{eqnarray}$$

The system is defined by the (A,B,C,D) matrices and the initial state x_0. The dimensions must be compatible.

Dialog box

• A matrix
  A square matrix.
  Properties : Type 'mat' of size [-1,-1].

• B matrix
  The B matrix, [] if system has no input.
  Properties : Type 'mat' of size ["size(%1,2)","-1"].

• C matrix
  The C matrix , [] if system has no output.
  Properties : Type 'mat' of size ["-1","size(%1,2)"].

• D matrix
  The D 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: yes
• 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: 0
• number/sizes of activation outputs: 0
• continuous-time state: yes
• discrete-time state: no
• object discrete-time state: no
• name of computational function: csslti
