In this paper, a state feedback controller is designed via polynomial method for a double inverted pendulum. The polynomial method is first extended into state space. ...
The two controllers share an identical state feedback control configuration, but their design procedures are different. It is found that the two different control methods have a similar performance. ...
Highorder controllers in modern control were also proposed using H ∞ and µ-synthesis theories [6] [7] . ...
