The bode plot of the open loop transfer function of a quadratic system is shown above. If the settling time of the closed loop system is 4 seconds, calculate the undamped natural frequency of the system, the damping ratio, the highest amplitude value of the frequency response of the closed loop system and at which input frequency it occurs. Attention!!!: Use the numbers as three decimals during the design phases. Solution: Belonging to the closed-loop transfer function Damping rate = [ ? ] Undamped natural frequency = [ ? ] rad/s The highest amplitude value of the frequency response [ ? ] and [ ? ] occurs at the rad/sec input frequency.
