摘要：The main purpose is to discuss some latest developments of singular distributed parameter control systems. Firstly, the well-posed problem of nonlinear singular distributed parameter control systems is discussed by using nonlinear generalized semigroup. Secondly, pole assignment of the linear singular distributed parameter control systems is discussed by using functional analysis. Thirdly, controllability of linear singular distributed parameter control systems is discussed by using operator theory. At last some problems are listed for further research. Singular distributed parameter systems are much more often encountered than distributed parameter systems. They appear in the study of the temperature distribution in a composite heat conductor, voltage distribution in electromagnetically coupled superconductive circuits, signal propagation in a system of electrical cables, etc. Well posed, pole assignment and controllability are three basic problems in the study of generalized distributed parameter systems.
