Contemporary approach to computer aided simulation of servosystems

Abstract

The approach to the problem of computer aided simulation is based on practical and easy-to-use realization of the servosystem operation in virtual (computer) reality. The simulation procedure is performed using the concept of state, numerical methods to solve differential equations (the Runge-Kutta method, the application of finite differences) and block-diagrams. A simple and efficient procedure to tune the integration step is given, so that the approximate equidistance of the state hodograph points is achieved and the growth of simulation errors, in case of fast changes of derivatives of state variables, is avoided.
