2 2.1 INTRODUCTION RL is a graphical presentation of the closed- loop poles as a system parameter (such gain) is varied A powerful method of analysis and design for stability and transient response. (Evans, 1948; 1950). 3 Walter Richard Evans (January 15, 1920 - July 10, 1999) The Control System Problem The poles of (b) cannot be determine unless factoring the denominator. The poles of T(s) change with K.

###### "Before using Course Hero my grade was at 78%. By the end of the semester my grade was at 90%. I could not have done it without all the class material I found."

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
