The study on variable structure partial model following control

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.
