State feedback is one of the important concepts in control theory. There are well defined methods like Ackermann's formula and Bass-Gura formula to find required gain matrix (K) which place close loop poles at the desired location. Here, instead of states, derivative of states are used in order to find the suitable control law. One of the applications of this type of feedback is vibration suppression of mechanical systems where feedback signal is generally taken from an accelerometer. Effectiveness of the proposed method is shown by simulation. (C) 2016 The Authors. Published by IASE.
