H∞回路成形中的μ综合法
μ-synthesis in H-infinity loop-shaping design
摘要
Abstract
Both loop-shaping design andμ-synthesis are standard design tools of the H-infinity control theory. Recently, a novel design method combining μ-synthesis with loop-shaping is proposed for dealing with the parameter uncertainty of the lightly damped mode. However, the practical design shows that such combination fails to provide the expected result. We point out that the loop-shaping design is essentially a method for robust stability, because the inverse of the resulting H-infinity norm is the stability margin of the system. However, the μ-synthesis is a real tool for designing the robust performance. The combination ofμ-synthesis with loop-shaping determines only the stability margin, but not the size of the allowable perturbation. Therefore, there is no need to add an extra procedure of μ-synthesis to the loop shaping design. A design example is presented for explanation.关键词
