Abstract
With the increasingly severe global energy crisis and environmental problems, the efficiency improvement of electric drive system and the research on energy saving technology have become important topics in the industrial field. This study aims to improve the overall energy efficiency of the electric drive system and reduce energy consumption by optimizing the control strategy and improving the system design. Through the method of theoretical analysis and experimental verification, the mathematical model of electric drive system is established and the key factors affecting system efficiency are analyzed; Secondly, an optimization algorithm based on fuzzy adaptive control is proposed to realize the precise adjustment of motor speed and torque; meanwhile, a new type of permanent magnet synchronous motor structure is developed to significantly reduce the iron loss and copper loss by improving the magnetic circuit design and cooling system. The experimental results show that, compared with the traditional method, the proposed optimization algorithm improves the system efficiency by 8.2% and achieves the energy saving effect by 12.5%. In addition, the temperature rise of the new motor structure is reduced by 15℃ under the full load condition, further improving the reliability and service life of the system.
