| Abstract: | Firstly the role of the rotary pressure signal generator is introduced in the system of wireless MWD, and based on the principle of the rotary pressure signal generator, a system structure models are designed, according to the different stages of the process, various process valves mouth.dynamic equation is established. Then according to the control signal of rotational speed and the degree, the system is simulate. |
