This paper proposes an experimental solution for H weighting functions selection by exploring an experimental planning method which is widely used in quality control. Conducting matrix experiments via orthogonal array, several parameters in H weighting functions can be determined efficiently so that the resulting controller is able to satisfy all design specifications. Of great importance, the proposed experimental method provides additional robust performance property to conventional H control which can only prove robust stability and nominal performance. Velocity controller design of DC servomotors is demonstrated to show the remarkable robustness and superior servo performance provided by experimental H design. A hardware environment is constructed to correlate the theoretical prediction and the measurement data. All specifications of robust stability and performance are validated by the experimental results.
