Added a proposal for closing the loop. Created two functions for simulation, one is a closed loop, the other is an open loop simulation.

Implemented closed loop simulation, and modified setup_params to return only one variable. This helps to make shorter lines, and reduces the number of variables to be assigned in one function call. IMHO, this improves code readability.
