【 摘 要 】

The dependencies of the simulation characteristics of simulators (for the preparation of the operators of transport ergatic systems) on the step of integrating the equations of motion of the Runge -Kutta control object of the second order of accuracy (updating the initial conditions at each integration step) are analyzed. Clarification of the time-dependent parameters of the control object (aerodynamic coefficients, mass, etc.) is made at each step. Approximate methods for estimating the effect of delay in subsystems (the latent period of the operator's motility, the play in the control channels, etc.) are given. An analytical evaluation is made of the dependence of the required integration step on the parameters of the control object. The admissible values of the integration steps are given for various criteria for estimating the integration accuracy. The methods underwent practical approbation when setting up a number of simulators of the dynamics of objects of ergatic systems.
