So i created a bode plot using margin() function and then multiplied my closed loop transfer function with the gain margin that I got from margin(). I created new transfer function for the system using X= feedback(K*G,1). When I made the step response graph with step(X), it didn't seem to oscillate indefinitely. What's wrong in my method?
Thank you foreahead for your answers!
Sincerely Yours, Jani
