Description

technical field [0001] The invention relates to the field of frequency converter control, in particular to a single-chip dual-core DSP frequency converter gradient model architecture control system and a design method. Background technique [0002] Electric transmission control system is widely used in machinery, mining, metallurgy, chemical industry, textile, papermaking, cement, transportation and other industrial sectors. 60-70% of the electricity generated by power plants is utilized by various electric motors. In the electricity consumption of motors, AC motors account for about 80%, most of which are directly driven by asynchronous motors. Due to the global energy shortage and environmental pollution problems, industrially developed countries have invested a lot of manpower and financial resources in the research of energy-saving measures for motors. It has been found that the loads of fans and water pumps, which account for more than half of the power consumption of...

Problems solved by technology

[0007] The above is the current status of the AC power transmission frequency conversion speed regulation control system and its development method. The current method cannot systematically and effectively realize the development method of the general AC drive control system with task decomposition and self-scheduling for specific production processes. This severely limits the R&D, manufacturing and industrialization of AC power drive control systems
