[Scilab-users] Steady state condition of o first order low pass filter

[Perrichon]

Hello Paul,

 

Thank you for this information, it works perfectly in one Xcos schema.

I ‘ve written a function in a sce file before starting xcos simulation, and
by adding a label « PB1 » and testing « gui=CLR », the procedure is more
general (see attached file).

 

Nevertheless, it is surely not well adapted in a stronger schema with
superblocks et more than one CLR block.

 

Also, I think that the right solution at the right place would be to modify
the CLR gui, by adding a case « Initial state », like in the Integrator with
saturation block (it should definitively slove this problem).

 

So, do you advice to write a bugzilla in the wishlist ?

 

Best regard,

Pierre

Hello Pierre,

Indeed you can modify that field in the block's "model.state" parameter (0
by default).
>From Xcos, Go to Simulation->Compile.
Then in Scilab (let's assume your block number is 3) :
 --> scs_m.objs(3).model.state = newInitValue; xcos_simulate(scs_m, 4);

Regards,
Paul

Hello,

 

Is there a way to initialize a first order low pass filter to an initial
value to its final value, in order to avoid any transitory at start
simulation ?

May be in a batch file and accessing to the scs_m CLR block register ?

But I don’t see where can I do it.

 

Do you have any idea.

In the following example, I want 1 in register up to time t=5s

Init value is not available in the CLR block.

 

Thanks for your response,

 

Sincerely

Pierre
