关 键 词：flexible systems H∞ loop-shaping H∞ norm robustness performance
摘 要：The control design of the flexible system and the specific flexible characteristics are related, from a control angle of the flexible system is divided into a shaft drive mechanism, the truss structure and the sheet-type structure into three categories. Obvious characteristics of flexible sheet-type structure flexible system design examples show that the H∞ loop shaping method can effectively solve the difficulties the sheet type structure flexible system design to ensure the stability of the system, that is a sharp decline in the amplitude-frequency characteristics band within. General H∞ control theory, H∞ norm is performance indicators. But the actual design of the H∞ loop shaping method H∞ norm is represented stability margin, only the design specifications, and its performance is determined by the weighting function of forming the loop shaping design H∞ controller used to meet the robust stability guarantee stability margin. The article also pointed out that the H∞ loop shaping method is not given perturbation range of design issues, so the concept of robust design is also different from the conventional H control design.
