| Abstract: | ag Free technology is a key technology for future space exploration, which put forward higher requirements for thrusters. The development and application of micro thrusters for drag free satellites are introduced based on the investigation of drag free technology space application. According to the development requirement for Chinese drag free propulsion, the dynamic model of the mass flow control of proportional valve for drag free cold gas micro thruster is built. A fuzzy adaptive PID controller is then proposed to improve the dynamic characteristics. |
