Three-Ring Genetic Control of Thermal Generator Based on Spindle Parameter Setting
The control accuracy of thermal generator has a great influence on the improvement of power generation efficiency.In order to further improve the accuracy of genetic control of three rings(position ring,velocity ring and current ring)of thermal generator,genetic algorithm is selected to adjust the spindle parameters.On the basis of identifying parameters to variable gain PI control,the convergence speed is realized by setting the inertia weight coefficient.The following performance is significantly improved by conducting the feed test from the aspect of linear signal.The results show that the following error is lower and the following performance is better under the feed condition.Compared with the manual experience method,the absolute error extremum and absolute error integral of the three-ring genetic control method are reduced by about 30％,and the following error is better and the following performance is improved.This research is helpful to improve the control accuracy of thermal generator and can be extended to other types of motor control fields.
