I can't create State Space Full Feedback Control structure in Simulink

1 view (last 30 days)
I determined the K vector by doing Pole Placement. A, B, C and D matrices are defined in Workspace.Here is the block diagram I want to create:

However, when I want to create this block diagram in Simulink, I cannot give the Step Input to the system?

Yes, “Multiply” Block accepts single Input only. You may have to do as follows:
  • Place a “sum” block with List of signs as “|+-”
  • Inputs to this "sum" block will be “Step” and “-K” blocks
  • Connect the output of “sum” block to “B” block
Hope this helps!
