摘要：

The property of regularity of singular systems is not a feedback invariant. To correct this deficiency, we define the new property of regularizability and give geometric tests for it in terms of system matrices. Regularizability is shown to be the natural extension of regularity, which is a condition on the homogeneous system, to controlled singular systems. Definitions of controllability and reachability are modified to depend on regularizability rather than regularity. A brief comparison of proportional and proportional-plus-derivative feedback laws in the context of making the closed-loop system regular, regular and reachable, regular and controllable is also given. Dynamical interpretations of these properties are also presented. © 1990 IEEE
