A Quasi-Newton Interior Point Method for Low Order H-Infinity Controller Synthesis
Daniel Ankelhed, Anders Helmersson, Anders Hansson · IEEE Transactions on Automatic Control · 2011
This technical note proposes a method for low order H-infinity synthesis where the constraint on the order of the controller is formulated as a rational equation. The resulting nonconvex optimization problem is then solved by applying a quasi-Newton primal-dual interior point method. The proposed method is evaluated together with a well-known method from the literature. The results indicate that the proposed method has comparable performance and speed.
