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

Calling Sequence

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

Parameters

• scs_m : a Scicos 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

Description

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

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