A method of robust control system design based on quality engineering and its application

This paper proposes a new method of robust control system design based on Quality Engineering. The appropriate order of the controller in transfer function form and its numerical values of the parameters can be determined by using the proposed method. The method is applied to a benchmark problem of dual-mass/ nonlinear-spring system. The result shows that the controller has comparable robust performance with He, controller and it is easy to reflect designer's intentions to the controller design. Then the industrial applicability of the proposed method is demonstrated through the design example of a vehicle chassis control system. The performances of the resulting controller are examined by stochastic robustness analysis.
