Research on stepless speed fuel supply based on pressure regulation

Due to the underwater thermal power system has the characteristic of big parameter variations, strong nonlinearity and other characteristics, it is difficult to achieve variable speed control. In this paper, we proposed a new way of stepless speed control of fuel supply, in order to realize precise control of the high-pressure fuel through regulating device, controller, driver and pressure generator. The simulation analysis and experiments showed that this method had rapid response, slight overshoot characters, and could meet the dynamic performance, stability and security requirements.
