摘　　要：永磁同步电动机系统是一类仿射非线性系统.该文应用非线性控制系统的几何理论对它的能控性与能观性进行分析,证明了永磁同步电动机系统在一定范围内是局部弱能控的、强可接近的和局部弱能观的.Permanent magnet synchronous machine system is a nonlinear affine system. Based on the geometric theory of nonlinear systems, the system controllability and observability is analyzed. It is shown that the system is locally weakly controllable, strongly accessible and locally weakly observable in a confined space.

关 键 词：永磁同步电动机 能控性 强可接近性 能观性 几何方法
