Design of a Robust H∞ Controller for a Magnetic Levitation System

Abstract:

Article Preview

The magnetic levitation system is nonlinear and inherently unstable. In order to improve its anti-interference performance and its loading capacity, a robust H controller is designed based on the H theory. The selection of the weighting function matrix is discussed for both the sensitivity and the complementary sensitivity of the H controller. Simulation and experimental results show that the H controller works effectively with excellent precision and robustness.
