【Abstract】 In this paper,double closed loop mathematical model of hydrostatic transmission system wih secondary regulation is established. A compalative study is carried out on single and double closed loop control system based on theoretical analysis and experimental research. The experimental results show that better control effects can be achieved with double closed loop control system than with single one.更多还原
