Embodiment Construction

[0027] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0028] The present invention provides a servo control method for an aviation stabilized platform under wide load conditions. The device used in the method includes a stabilized platform 1, a load transfer barrel 2, an optical load 3, a power supply 4, a control computer 5, a control cable 6 and power supply cable 7, such as figure 2 shown.

[0029] The stable platform 1 has three axial movements of pitch, yaw, and roll. The three shafting motors drive the axial movement of the stable platform 1 in three directions respectively. The torque of the shafting motors has a margin to load the stable platform 1. The upper limit value is based on the selected shafting motor torque; the frames of the stable platform 1 are all in the form of holes, that is, the pitch frame, yaw frame, and roll frame are provided with hole structures, and are connected to the extern...

Abstract

The invention discloses a servo control method for an aviation stable platform under a wide load condition. Classification is carried out according to the load weight, parameter design is carried out for each weight interval, the interval corresponding to the load weight is selected, and the parameter of the lower limit value of the corresponding interval is used as rough Tuning parameters, directly adjusting the fine-tuning parameters through the interactive interface, to achieve good servo control performance; moreover, this method is easy to operate, and the calculation time is short, and the torque motor with large torque margin is used to realize a large adjustable load range, which improves the load capacity of the stable platform Efficiency, which solves the problem of poor versatility of the stable platform.

Description

technical field [0001] The invention relates to the field of servo control systems, in particular to a servo control method for an aviation stable platform under wide load conditions. Background technique [0002] In recent years, with the development of optoelectronic technology and the continuous improvement of measurement and control technology, the application of optoelectronic stabilization platforms in the aerospace field is increasing. In the process of optical remote sensing aviation operations, the main reason for the decline in the quality of payload imaging is that it is disturbed by the "jitter" of the attitude of the aerial platform, and the visual axis of the optical system shakes, resulting in blurred images. At present, in the field of aerial remote sensing, a stable platform is installed on the aerial platform to perform attitude compensation in the three directions of pitch, yaw, and roll, so as to isolate external disturbances and achieve the effect of sta...
