Sensor quantization method for space optics effective loading force disturbance simulation source actuator

Abstract

The invention provides a sensor quantization method for a space optics effective loading force disturbance simulation source actuator and belongs to the technical field of testing space platform micro-vibration environmental adaptability through space optics effective loads. The sensor quantization method aims to realize the space optics effective loading force disturbance simulation source actuator. The method comprises the step one of determining a control loop type, the step two of determining a sensor type and the sensitivity, the step three of determining the control range and the minimum control step size, the step four of determining the sensor quantization bit width, and the step five of carrying out gain compensation on sensors of a loop. The method achieves the effect of sensor quantization of the space optics effective loading force disturbance simulation source actuator, normalization processing and resolution setting of multi-sensor quantization of the loop are controlled, and the situation that due to the fact that in a digital controller, a large number of division operations are guided into the sensor normalization processing, the operation performance and the control precision of the controller are reduced.

Description

technical field [0001] The invention relates to a sensor quantification method for a force disturbance simulation source actuator of a space optical payload, and belongs to the technical field of adaptability testing of a space optical payload to a micro-vibration environment of a space platform. Background technique [0002] The space optical payload is a special imaging device carried on the satellite to obtain the optical information of the target of interest. Under the same application conditions, in order to obtain high-quality and high-resolution images, the volume and aperture of the optical load are getting larger and larger, and the requirements for the micro-vibration environment of the satellite platform on which it is located are also getting higher and higher. The environment of the satellite platform where the optical payload is located is micro-vibration due to the movement of the mechanism, the tremor caused by the cold and heat of the solar panel, and the di...

Problems solved by technology

[0003] However, there is no uniform micro-vibration ground test verification method for high-resolution space payloads. Most of the test methods are oriented to component-level equivalent models, and they are also consistent with the actual on-orbit payload in terms of micro-vibration degrees of freedom and coupling paths. The environment is very different, and there is no report on the ground verification test method for the micro-vibration of the remote sensor. The ground test is still in its infancy, and the testing technology and means are limited. The satellite platform micro-vibration source simulation method and the corresponding space optical payload force disturbance simulation source actuator control loop sensor quantification method are also a technical blank
