Abstract

The article is dedicated to the optimization of vessel operation at casting of purse net. The aim of the research is to increase the productivity of the fishing vessel by reducing the number of failed castings of purse net. To achieve the goal the problem of optimal algorithm of a vessel control at casting of purse net is solved. As a result of solution of particular problems, the optimal planning methods of mechanical trajectory of a vessel at casting of purse net were used, as well as mathematical model of change of angular velocity in a function of rotation, with the influence of the net. Optimal planning of the actual trajectory at casting of purse net is carried out by the inverse method, taking into account the control object specificity. This method allowed the minimization of the probability of error to get the starting point of net casting at his return, through the introduction of reserve of control actions. According to the result of the first experiments of the system simulation in MatLab, the average error of the vessel getting to the starting point of the trajectory constitutes 3% of the length of the net. It should be noted that the problem was simplified at this stage, i.e. external disturbances (wind, sea state, etc.) were not taken into account.
