英文摘要： As aggravation of the market competition and the need for enterprises self-innovation, the demands for manufacturing process and quality characteristics of complex products are higher, and the relationship between forming and influencing factors of quality characteristics has shown pluralism. To guarantee the demand for multi-phase and multiple quality characteristics in complex products manufacturing process, the nonlinear coupling quality control method and theory are proposed based on fractal network theory. The relationship between multiple quality characteristics and influencing factors is researched, the inherent law and evolution mechanism of nonlinear coupling among multiple quality characteristics is revealed, and the nonlinear decoupling method, based on the nearest-neighbor coupled weighted networks models, brittleness theory and nonlinear control theory, is researched to solve the difficult in key quality monitoring, quality data self-correlation, the multiple factors tracing of quality characteristic errors and the statistical state of quality characteristics with the integration of feedback control. Finally, the proposed method will set the foundation for the nonlinear coupling quality control, and provides a new control and improvements strategy for complex products state in the levels of control
