Simulation of the Processes and Analysis of the Selfoscillations in a Free Nonlinear Torque Controlled Crane System

摘要

A precise method for simulating and determining the parameters of self-oscillations in systems with piecewise-linear nonlinear elements is described. The method is based on the nonlinear system representation by means of equivalent linear descriptions. The period determination is reduced to the combined solving systems with linear and nonlinear equations. The application of this method to the simulation of the processes and analysis of the self-oscillations in the nonlinear torque controlled crane system is described. The algorithms and programs are developed. Standard program products are used for solving the linear and nonlinear sets of equations. Some simulation results for different initial values are shown.
