Constructs by linearization a linear state-space model from a general dynamical system described by a xcos diagram

Calling Sequence

sys= lincos(scs_m [,x0,u0 [,param] ])



Construct a linear state-space system by linearizing a model given as a xcos diagram.

The output is a Scilab data structure of type continuous-time state-space linear system.

sys= lincos(scs_m [,x0,u0 [,param] ])


  • scs_m : a xcos data structure

  • x0 : column vector. Continuous state around which linearization to be done (default 0)

  • u0 : column vector. Input around which linearization to be done (default 0)

  • param : param: list with two elements (default list(1.d-6,0)) param(1): scalar. Perturbation level for linearization; the following variation is used del([x;u])_i = param(1)+param(1)*1d-4*abs([x;u])_i. param(2): scalar. Time t.

  • sys : state-space system
