Dab483: Sorry the command clean is a bug. It comes from the scilab version where is used to eliminate unnecessary decimals. Please just delete the command.

This functions are showed in the next table.

dss2tf----- Descriptor system state space to transfer function
dcontr----- computes C, R and I controllability
dobsv------ computes C, R and I observability matrices
dstabil-----Computes the stability
qrrse-------Computes the QR restricted system equivalence (r.s.e.)
invrse-------computes the inverse r.s.e form

There contain some observers for state estimation. This observers are based
principally in the works of (Darouach1995s, Darouach1996, Hamdi2009, Hamdi2011)

abcdcoeff---- a,b,c and <d coefficients for Darouach observer
darobsv95---- Full order observer
redobsv95---- Reduced order observer
darobsv96---- Reduced order observer with unknown input
puiobsv------ Proportional unknown input observer (PUIO)
piuiobsv----- Proportional-integral unknown input observer (PIUIO)

For fault detection applications the following commands compute automatically
the gains to generate a bank of observers. This bank of observers
are based in a proportional and a proportional-integral unknown input observer
(PUIO and PIUIO).

gosbank1--- For a generalized observer scheme (GOS) with some of the observers
mentioned

dosbank2-----For a dedicated observer scheme (DOS) with some of the observers
mentioned.

The put the observer in a stability region the LMI are solved with the
LMITOOL of Scilab.

And finally for analysis, state estimation and fault detection of LPVD system:

lpvpuiobsv---- LPVD Proportional unknown input observer
lpvpiuiobsv--- LPVD Proportional-integral unknown input observer
lpvweig4------ For the construction weighting functions of 4 vertices.
lpvweig3------ For the construction weighting functions of 3 vertices.
lpvweig2------ For the construction weighting functions of 2 vertices.
lpvgosbank1---- For create a bank of oservers using a generalized observer
scheme (GOS)

17 May 2011 Several methods for Solving DAE cases using Simulink and S-fucntion Try to solve DAE case using Simulink and S-function, compared the results and CPU time. Author: Fengcheng Sun

What happend when we have 2 algebraic equations. Given the nex dae system:

dx1/dt=2x2u
dx3/dt=x1
-x1+x4=0
x2+x3+x4+input=0
when input should be a sine or step input

27 Feb 2011 CaToKi V2. System Identification ToolKit in Open loop SISO. Is an easy tool for system idenfication of real procces. Author: Francisco-Ronay Lopez-Estrada

This work in Matlab 2010b. Only change the formats of the next figures from jpg to png.
ChargeData.jpg-->ChargeData.png

Is a problem with new versions of matlab.

Hi, why do i get this? Tqs

??? Undefined function or method 'clean' for input arguments of type 'double'.

Error in ==> lpvpuiobsv at 135
H1(:,:,j)=clean(H12(:,1:a));
