Dynamic positioning ship synchronous convergence control method based on finite time

Номер: CN116360463A
Принадлежит:

The invention discloses a dynamic positioning ship synchronous convergence control method based on finite time. The method comprises the following steps: establishing a dynamic ship kinematics and dynamics model; establishing an error dynamic equation according to the kinematics and dynamics models and an expected position; designing a sign function, and designing a synchronous convergence sliding mode surface according to the sign function; and designing a finite time convergence synchronous controller according to the sliding mode surface and the Lyyunov stability. According to the control method, synchronous convergence of errors of all degrees of freedom of the dynamic positioning ship can be achieved, control parameters are few, and the form of the controller and the workload of parameter adjustment can be effectively simplified.

Construction method of marine organism single cell transcriptome library

Номер: CN116536394A
Принадлежит:

The invention relates to the technical field of gene engineering, in particular to a construction method of a marine organism single cell transcriptome library. The construction method comprises the following steps: obtaining cDNA, performing PCR amplification, and establishing a library; the step of obtaining the cDNA comprises water-in-oil preparation and reverse transcription; the step of preparing the water-in-oil comprises a step of mixing a cell phase, a beads phase and an oil phase; the volume ratio of the cell phase to the beads phase to the oil phase is (3-4): (5.5-6.5): (21-23). According to the water-in-oil system for optimizing reverse transcription, the unicells of marine organisms are not easy to break when water-in-oil is formed for reverse transcription, sequencing data with better quality can be obtained after sequencing, and the detection efficiency and accuracy of marine cells are remarkably improved.
