As the National Two Sessions in March 2021 put forward "Insist on innovation-driven development and comprehensively shape new development advantages", my country is facing in-depth manufacturing reforms, and the proportion of localization of high-end equipment manufacturing will further increase. Therefore, the study of the high-efficiency, high-precision, high-reliability induction motor variable frequency speed regulation system with independent intellectual property rights is of great significance to promote industrial upgrading and high-quality development, and is in line with the "The Fourteenth Five-Year Plan of National Economic and Social Development of the People's Republic of China" The Strategic Needs of the Annual Plan and the Outline of the 2035 Vision Goals.

Hande-Harbin Institute of Technology cooperated with industry-university-research institutes to develop "speed adaptive full-order observer control algorithm", realized the localization of Siemens vector control algorithm and ABB direct torque control algorithm (DTC), and obtained four core invention patents. Two invention patents. It broke the monopoly of Siemens vector control algorithm and ABB direct torque control algorithm in the domestic market. Promote the localization of my country's inverter technology, software and hardware, and enhance the localization capabilities of high-end inverter technology.
