英文摘要

      In this paper, the new concept of partial model following control (PMFC) is proposed for multivariable linear mismatched uncertain systems. Based on the variable structure control theory, a specific structure and a design method of the variable structure PMFC systems are studied. Moreover, an independent design theorem between the sliding mode and the specific structure is proved, the maximum following ability of a PMFC system is also determined. So that the strict confinements of the invariance conditions are broken through, and the system steady-state following performances are greatly improved.
