Embodiment Construction

[0032] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0033] An active attitude control method of a modular mobile phone star, the specific implementation steps are as follows:

[0034] Step 1: Establish the state equation of the mobile phone star

[0035] like figure 1 As shown, a conjoined coordinate system X is established on each module of the modular mobile phone star 1 Y 1 Z 1 , X 2 Y 2 Z 2 and x 3 Y 3 Z 3 and the inertial coordinate system X 0 Y 0 Z 0 . Conjoined coordinate system X of module 1 1 Y 1 Z 1 Relative to the inertial coordinate system X 0 Y 0 Z0 The three rotation angles of [θ 11 ,θ 12 ,θ 13 ], the conjoined coordinate system X of module 2 2 Y 2 Z 2 and the conjoined coordinate system X of module 3 3 Y 3 Z 3 Respectively relative to the connected coordinate system X of module 1 1 Y 1 Z 1 The rotation angles are θ 2 and θ 3 , choose these five rotation angles as the gener...

Abstract

The invention discloses an active attitude control method of a modular mobile phone star. Inspired by the maneuverability of animal attitudes in nature, the invention changes the relative attitude of each module through the drive of the active joints between the modules, thereby changing the overall mass distribution , under the principle of conservation of angular momentum, the phone star will maneuver from the initial attitude to the desired attitude. The modular mobile phone satellite attitude control method proposed by the present invention comprehensively considers energy consumption and control error, requires low power consumption, and has high control precision; fully considers the actual constraints faced in the project, and ensures that the actuator does not exceed the maximum execution it can withstand Torque, to ensure that the initial value and final value of the output torque of the actuator are both 0, which improves the stability of the attitude maneuver; the required actuator is simple to install, light in weight, and occupies a small space, which overcomes the limitations commonly used in micro-satellite attitude control. The magnetic torque device is difficult to install, has low installation accuracy and takes up a lot of space.

Description

technical field [0001] The invention relates to the field of micro-satellite attitude control, in particular to an active attitude control method of a modular mobile phone satellite. Background technique [0002] In recent years, due to its significant advantages such as low launch cost and short research and development cycle, mobile phone satellites have broad application prospects in space environment detection, military investigation, and new technology experiments. Among the active attitude control methods of mobile satellites, the most commonly used method is to use the earth's magnetic field to achieve satellite attitude control. This method uses a magnetic torque device as an actuator, and uses the principle that a energized coil is subjected to a magnetic force in a magnetic field, and then generates a magnetic torque to realize physical movement. However, since the common magnetic torquer (whether it is a magnetic rod type magnetic torquer or a hollow magnetic tor...
