 Notes: In theory, SSE should decrease following the increased Ki, but i suspect Matlab just can't compute too much floating point. Hence, i add two additional test with larger constant to show the effects.
 
 ## Additional Testing
 For Kp = 50

+## Conclusion
+Based on previous tests, we conclude that by adding Integral constant :
+* Risie time is **increased**
+* Settling time is **increased**
+* Overshoot is **decreased**
+* SSE is **decreased**
