Based on the research situation of the parallel I/O data scheduling policies,a new data scheduling policy named the dynamic I/O scheduling algorithm of two times scheduling and self-maintenance load balancing(DIO_TSMB) is proposed.

Application of the technique of hydrostatic transmission with secondary regulation in engineering machine multi-function experimental platform;

On energy-saving and speed control of secondary regulation lifting system of parking equipment;

Analysis on dynamic performance of servo loading system with secondary regulation;

This paper describes the relationship between the hydro-turbine governor and the grid load frequency control, analyzes the functions, the static and dynamic characteristics of the governor in grid primary and secondary frequency regulation.

Through the software primary and secondary frequency regulation, the system complete the frequency regulation work in isolated power grid and guarantee the operation stabilization of the plant.
