抜粋

This paper presents a new controller design methodology for an electromagnetic suspension system using the Q-parameterization theory and μ-analysis, in order to achieve both robust stability and robust performance. The set of all stabilizing controllers of the plant is characterized by a free parameter Q. This free parameter is chosen through optimization such that both robust stability and robust performance are achieved. First, we describe the experimental setup and give a mathematical model for the electromagnetic suspension system used in this research. Second, we explain the Q-parameterization control with μ-analysis of a given plant. Third, we formulate the control problem as an optimization problem in the free parameter Q with robust stability and nominal performance as constraints and we assess robust performance with μ. Fourth, the proposed controller design methodology is applied to the simple SISO electromagnetic suspension system employed in this research and a fifth order controller which achieves both robust stability and robust performance is obtained. Finally, several simulation and experimental results are presented. The results showed the effectiveness of the proposed controller design methodology.
