Compare the result from Part 2 of the Lab Procedure to determine how PI control can be used to meet the desired control performance specifications in simulation. Provide Matlab plots of the closed-loop step responses using the original PI gains from Step 13 and your tuned gains from Step 15. In addition to these plots, provide a table that includes the control gains, measured percent overshoot, and measured settling time using both the original and tuned controller. Discuss how you tuned the control 23 gains, how the values of the PI gains changed from the original to the tuned values, and any difficulties you encountered in achieving the performance specifications
