Closed access Metadata (CSL-JSON)
DOI 10.30919/es1130
Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The article discusses the problem of synthesizing a system for stabilising the movement of an object along a given trajectory.Solving the control synthesis problem involves finding the control function on the deviation of the object from a given trajectory.A trajectory stabilisation system is necessary for the object to maintain its trajectory under real conditions in the presence of external disturbances.In the work, machine learning control by symbolic regression was used to solve the control function synthesis problem.Symbolic regression methods allow to find the mathematical expressions of the desired functions in the form of special code.To find the mathematical expression of the desired function, the symbolic regression method uses a special genetic algorithm that searches the code space for the optimal solution according to the given optimisation criterion.An example of motion stabilisation of two quadcopters along optimal trajectories is presented.
