Inertial stabilization controller

Abstract

The invention discloses an inertial stabilization controller. The inertial stabilization controller comprises a main control module, an orientation motor driving module, a pitching motor driving module, a roll motor driving module, a rate gyro acquisition module, an angular position acquisition module, a data storage module, a serial port expansion module, a management control module, an inertial navigation module and a secondary power source module. The inertial stabilization controller integrates functions of driving, acquisition, storage, communication and synchronization into one body and greatly ameliorates a problem of single function of an inertial stabilization controller in the prior art. The inertial stabilization controller can eliminate influence of high carrier aircraft and low frequency disturbance on pendular or tracking imaging systems, is applicable to a single-axis, two-axis or three-axis inertial stabilization platform, has a wide application scope and is successfully applied to multiple models of aviation optical remote sensors.

Description

technical field [0001] The invention relates to a multi-axis multi-functional high-precision inertial stability controller, which belongs to the technical field of aerial optical remote sensing. Background technique [0002] In the field of aerial remote sensing, the imaging system is often subject to external disturbances, such as wind speed, vibration of the aircraft, etc., which will greatly reduce the imaging quality. In order to ensure imaging stability in inertial space, a general inertial stability controller is proposed. In the past, most controllers used a single-axis or dual-axis stable structure, that is, to control the movement of the visual axis along two rotational degrees of freedom that are orthogonal to the visual axis and perpendicular to each other, and keep the visual axis stable. However, this dual-axis stabilized platform Ignoring the disturbance of the third direction axis, it can only be applied to the case where the external environment has little i...

AI Technical Summary

Problems solved by technology

The current motor controller is relatively mature, but the motor driver in the inertial space in the field of aviation remote sensing is not yet mature, especially for multi-axis, multi-sensor, and multi-functional drivers. There are still the following problems: (1) According to the different requirements of the indicators , the selected actuators, sensors and quantities are uncertain, and different drive modules and acquisition modules need to be configured for different projects; (2) The versatility and inheritance are poor, and the sensors that cannot be compatible are digital or analog, which is not conducive to Sensor Replacement
