Research of disc valve friction torque modeling and integral sliding mode adaptive control for rotary steering drilling tool

There is a clear non-linear characteristic of friction torque to the control axis on stable platform control system. Based on the structure of this system, the article establishes the basic model of the control system and the disk valve model of friction torque. For the non-linear friction torque, i...
