How can I set block mask parameter from subsystem input
显示 更早的评论
Hello.
I am new to simulink. I am using simscape hydralic and mechanic blocks to create my library subsystem piston model. I would like to initialize "Piston initial position" of "Hydralic Piston Chamber" from my subsystem input. This input would be connected to other block output, which calculates initial position according to cam geometry.
I am able to create subsystem mask parameter as variable to the block, but I don't know, how to initialize this variable from other block. Constant block can be used as variable source; I miss a block targeting port signal to a variable.
I would like to have my piston model independent of base or model workspace.
I would be glad for any help or advice.
Thanks.

It is currently not possible to treat dialog parameters such as "Piston initial position" as an input. Please see the blog post How Do I Change a Block Parameter Based on the Output of Another Block? to understand why you cannot do what you want described in the question. Since the initial position is only used once, at the beginning of simulation, do you really need to use another part of the model to compute it? It seems like it should be a static computation (maybe using MATLAB code), rather than a dynamic computation.
