Research on Adaptive Power Control System of Working Machinery

The load changes of working machinery in the running process will certainly result in poor matches in the characteristics of the transmission system. For the issue, this paper studies the adaptive power control model and algorithm. The adaptive power control system is developed using the adaptive power control technology based on the load identification, and is applied in the full AC electric forklift and the CNC band sawing machine. The variable frequency system and intelligent control method based on the integration of the load characteristic recognition and control proposed in this paper, adaptively adjust the parameters of the PID controller according to the load characteristic parameters identified real-timely for the transmission system of the working machinery, so as to achieve the best performance matches, the highest effectiveness and lowest energy consumption of the entire transmission system.
