I'm developing a motor controller in Simulink, and I have more than one motor that I want to simulate with. I'd like to adjust the motor parameters in an elegant way that experienced Simulink developers would recognize the design pattern. When I'm done, I want to be able to hand this simulation off to another engineer and have a non-simulink expert understand how to switch motors and preferrably be able to add a new motor variant in the future. I am considering the following approach, but would like feedback on whether there is a more "Simulink" way to solve it:
I have a subsytem which contains the Simscape Electrical BLDC block and a Hall sensor signal generator. The subsystem block defines the Motor parameters for the variety of motors that I can select. The subsystem mask has a dropdown box to select which motor is being used for simulation. The subsystem InitFcn() updates the BLDC parameter values based on the setting of the dropdown box.
An alternative would be to write a .m file for each motor, and then select which .m script is run during InitFcn(), but I'm not sure I can add a file dialog to the subsytem mask. What I like about this is I can add as many motor variants as I want by just writing another .m file.
Any advice on best practices is appreciated!
