An extended high gain state and perturbation observer combined with feedback linearization was applied in drag tracking for Mars entry longitudinal guidance. The observer estimates the drag
the drag rate and the perturbation due to model uncertainty and disturbance for drag tracking. Mars entry simulation was performed to assess the performance of the adaptive guidance law. The results demonstrate that the proposed guidance law is robust to model error
and can recover the ideal performance of the feedback linearization control. Introduction In recent years
the concept of pinpoint landing has been proposed (2013) Trans Tech Publications

According to the area CCD camera of characteristics
such as high resolution capacity and high frame frequency
this paper puts forward a high speed and parallel image compression system of high integration degree. Firstly
according to the work principle of the area CCD
FPGA is adopted to realize the timing driving and multichannel and parallel analog signal handling to raise the export frame frequency of the area CCD. Secondly
with an image compression scheme based on FPGA embedded processor MicroBlaze and ADV212 compression chip
real time image compression and the high speed area CCD are realized. Finally
by detecting the analog signal of the area CCD output
the real time compression of the big area CCD image is carried out in different compression ratios and the compression performance is analyzed. Experiment result shows that this scheme can realize real time image compression with the biggest data rate of 520Mbps. When compression bit ratio is 0.15
the signal-to-noise ratio of peak value can reach 36 dB. Image collection and image compression are integrated
which reduces the data transmission between them and improves systematic integration degree.
