Under weak control with strong architecture conditions, frequency converter speed regulation systems face the contradiction between insufficient control flexibility and low energy efficiency utilization. This paper proposes a speed regulation method that balances energy efficiency optimization with structural adaptability through analysis of system operating characteristics and structural constraints. Starting from motor load characteristics, speed regulation strategies, and energy transfer paths, the study integrates the fault-tolerant advantages of weak control strategies with the stability under strong architecture conditions to construct a multi-dimensional energy efficiency improvement model. Experimental results demonstrate that this method effectively reduces system losses, enhances overall energy utilization efficiency, and achieves coordinated optimization of power and efficiency while maintaining operational stability. This research provides a feasible technical approach for energy-saving control of frequency converters in weak control with strong architecture environments.
