Problems solved by technology

Nano-satellites are small in size, small in inertia, and light in weight. They are affected by many unknown disturbance moments during flight, and long-term accumulation will cause the satellite attitude to deviate from the predetermined ideal state and affect normal operation.

Abstract

The invention provides a device and a method for controlling a flight attitude of a micro / nano satellite. The device comprises a fuzzy adaptive PI (Proportional-Integral) controller, a driver, a high power density motor and a flywheel body, wherein the fuzzy adaptive PI controller is used for sending an adjustable duty ratio pulse signal to the driver; the driver is connected with the fuzzy adaptive PI controller, and used for converting the adjustable duty ratio pulse signal into an angular momentum control signal and sending the angular momentum control signal to the high power density motor; the high power density motor is connected with the driver, and used for controlling the flywheel body according to the angular momentum control signal; and the flywheel body is connected with the high power density motor, and used for outputting variable angular momentum under the driving of the high power density motor to control the flight attitude of the micro / nano satellite. The device for controlling the flight attitude of the micro / nano satellite has the advantages that the device can adaptively absorb various disturbing moments during an on-orbit period, responds at superspeed, is high in accuracy, has a zero tracking error, and can adaptively resist external disturbance.

Description

technical field [0001] The invention belongs to the technical field of satellite attitude control, and in particular relates to a micro-nano satellite flight attitude control device and method. Background technique [0002] With the development of high and new technologies such as micron / nano, the research on nano-satellite technology under 10 kg has become one of the hotspots in international satellite technology research. Countries have vigorously carried out research on micro-nano-satellite technology, so that it can be used in military affairs, communications, geological exploration, environment and disasters. There can be more specific applications in monitoring, meteorological services, scientific experiments, and deep space exploration. As one of the key satellite technologies, attitude control plays an important role in the implementation and completion of flight missions. The reaction wheel / momentum wheel of the nano-satellite attitude control actuator is installed ...
