Based on the robust theory for multivariable systems and the concept that the feedback can decrease the effect of plant parameter variations on the output, this paper presents a design method for robust systems and an algorithm for designing inner feedback gain matrix. The method is applied to designing a robust control system for a practical industrial plant with satisfactory results. It is shown that, for the theoretic analysis and the design examples, the resulting system using this method exhibits better robust stability and robust properties in comparison with the robust design method using series compensation.
