I am working of super twisting sliding mode control design for electric dynamic load simulator
i have used ode45 for that, now how i can import data for system identification. plz guide
[t1 x1]=ode45(@STSMC_ELS, [0 2], [0 0 0]);
Dear Chandar Kumar
The result for ode45 in your case is x1, and also I think you have another output which is x2. these two variables are changing over time, so they are called time-domain data. Then, you should open the system identification toolbox in MatLab. It is a really simple and user-friendly toolbox. Then you must import these to variables in the toolbox, and estimate your model.

-------------------------------DIRECTION TO Solve----------------------------------------
- First step (Basic):
For example, suppose you have two outputs (means x1 is a vector), and you want to plot "y1" versus "t" and "y2" versus "t" from
[t1 x1]=ode45(@STSMC_ELS, [0 2], [0 0 0]);
then you have to write following Matlab Commands.
1. t=t1;
2. y1= x1 (:, 1) ; y2=x1(:, 2),
3. plot(t, y1, t, y2)
- Second step (apply toolbox):
Apply the system identification toolbox in MatLab as said by @Hamid Keshmiri Neghab.
-----------------------------------------THANKS--------------------------------------------
[t1 x1]=ode45(@STSMC_ELS, [0 2], [0 0 0]);
function dx=STSMC_ELS(t,x)
dx=[x1dot; x2dot; x3dot]
where x1dot is angular position of motor
x2dot is angular speed
x3dot is error
now plz guide it is correct to import: input t1 and output x1 ?
not something else
