  • Page 20: Control System Description

    MUGL Page 20 of 38 rev. 18 November 2009 10.2 Control system description The control system is based on two PID loops in sequence, named “Inner loop and Outer loop”. The inner loop is the fastest and will adjust the current in the load. It takes as input the reference of the outer loop The outer loop regulates the output voltage, reacts more slowly and it provides the value of current to the inner loop.

  • Page 23: Technique For Adjusting The Loops

    MUGL Page 23 of 38 rev. 18 November 2009 10.5 Technique for adjusting the loops The adjusting of PID loops must be done in two phases, first the inner one and then the external one. In order to adjust and verify the dynamic performances, it’s better to have a dynamic load at the output so to visualize the voltage variations with respect to the load variations.
