| Abstract: | This paper presents a new method of estimating dynamic parameter of a secondorder underdamped system. The method uses samples of the step response signal and does not require a priori information about step function amplitude and damping ratio.angular natural frequency of the system. Mathematical development of the algorithm is presented and its accuracy is illustracted in a simulative test. |
