Can I make an inquiry about another two problems about simulink modelling? The problems are shown in the attached picture.
This is a subsystem to model the variable speed control unit for my system. But I was struggling with connection thing.
1) the position 1 and 3 are two kinds of connection ports(simspace(left), powertrain(right)), but if I use the connection ports in subsystem, it seems cannot be connected with other blocks in the parent system.
2) for the simspace and powertrain block connection, shown as in postion 2, I used the sensor and ps_s converter, but it cannot be connected to the powetrain block port.
I am a beginner now, and now seems I dropped into a dead cycle, if using connection port here and it can help connect, but again it cannot be connected at another place. Could you please give me some hints and help about this?
Thanks, and looking forward to your reply.
