(OP)
Im doing my Simulink assignment. I need to control a current(output), make it follow a given trajectory. The input is pulse-width modulated. In other words, the input is a serie of square pulse. The output, thus, depends on the width of the input pulse.
  Gives the cycle of the input is T, the width will be: mT (0<m<1). Using m, I can control the output. I implemented the system in Simulink. I'm using the Pulse Generator Block for the Input.
  
  The problem is, how to extract the parameters of the Block, and how to change it from other blocks????

  Thank you very much.
