The invention provides a driving control method for a satellite solar wing sailboard. The driving control method is composed of a novel driving and control method for solar wing sailboard swinging, a method for solar wing sailboard zero position returning, an automatic calibration method for a solar wing sailboard swinging precision period and the like. A central processing module receives a remote controlling command sent by an on-board computer in real time and drives and controls swinging of the solar wing sailboard according to the content of the remote controlling command. Meanwhile, a Hall sensor installed at the end of the solar wing sailboard feeds back the position information of the solar wing sailboard, and feeds back telemetering data to the on-board computer according to the controlling information of the solar wing sailboard. The mechanical zero position of the solar wing sailboard is calibrated through the information of the Hall sensor, the step number and the direction which are used for driving a stepping motor to rotate are combined, so that the functions that the automatic calibration of the position information of the solar wing sailboard in each period is achieved and the solar wing sailboard can be stopped in the mechanical zero position are achieved. The driving control means of the satellite solar wing sailboard are expanded, and the driving control method can be directly applied to the driving control tasks of various types of satellite solar wings in China.
Description
technical field [0001] The invention relates to a driving control method for a satellite solar wing sail, which can be applied to the drive control task of a satellite solar wing sail. Background technique [0002] The rotation or swing of satellite solar wing panels is an important way to realize solar wing battery arrays tracking the sun and generating electric energy with maximum efficiency. The development cycle of the satellite solar wing sail puts forward higher requirements for the driving control method. [0003] At present, the commonly used satellite solar wing sail panel drive control method is realized based on the CPU module plus a full-bridge circuit. The method generates the pulse signal and rotation direction signal required for the rotation of the stepping motor, so the technical level of the software developer is relatively high, the development process is relatively long, and the accuracy of the pulse signal will vary due to different software developers....
