INCREASING CONTROL’S EFFICIENCY FOR THE SHIP’S TWO-MASS ELECTRIC DRIVE

Purpose. For shipboard lifting and transporting machinery (LTM) with AC thyristor electric drives (ED) the problem of minimizing sway through the formation of the special law to change the principle of ED control over the lifting process is solved. Methodology. This goal was achieved through the fol...

Methodology. This goal was achieved through the following objectives: analysis of current studies on the reduction of the negative effects of load fluctuations, fixed on the suspension with variable parameters; determining the criteria to optimize the movement of the lifting mechanism and transfer control laws under which the load fluctuations are reduced; develop the methodology and experimental study of the main characteristics of the mobile model ED lifting mechanism with its load suspended from the perspective of both the parameterization of the control system (CS) as well as elements of ED. For realization of tasks in research methods of mathematical modeling of dynamic processes on the computer, structural methods of control theory, experimental studies in the laboratory setting have been used. Results. Based on analysis of current research can be concluded that the stability of the ED of LTM to the disturbing points provided coincidence zero electric coordinates and speed deviation diametric plane of the vessel from the vertical position. Criteria for optimizing CS used by the ED LTM mathematical description of its dynamics differential equations to the estimated coefficients derived from the functions of state variables.
