Application of Parametric Sensitivity Method to Analysis of Automatic Mooring Winch with Electric Drive System

This paper presents an improved model of nonlinear actuator, as example of three-phase asynchronous motor, being an integral part of automatic mooring winch. For such technical objects, a mathematical model of auxiliary parametric sensitivity was developed, which becomes the real unifying factor that make it possible to analyze the nonlinear technical systems based on general theory of nonlinear differential equations combining into one algorithms all stages of analysis: calculation of transitive and steady-state processes, determination of static stability and parametric sensitivity.
