1. What are the main considerations for selecting initial conditions for solving dynamics equations using Matlab Simulink. For instance, setting the initial conditions in the continuous state block or integral block?
2. Is it possible to use a mathematcal expression or relation instead of a number as the initial condition in the integral block of Simulink?

  1. The initial conditions are set to represent the initial conditions of the system to be simulated. What other considerations might there be?
  2. Yes. Any expression can be used that returns a value that is consistent with the requirements for the initial condition of the block in question.
