POSSIBLE METHODS FOR QUALITATIVE IMPROVEMENT OF PRECISION CHARACTERISTICS OF SYSTEMS FOR CONTROLLING MOTION PATHS OF SHIPS, MISSILES,AIRCRAFTS AND OTHER VEHICLES

摘要

The results of development and synthesis of center-of-mass motion control method for mobile objects like seagoing ships, riverboats, aircrafts, guided missiles that use steering engine, representing an integrator, for activating object executive elements are presented. Two requirements of positional invariance are well-grounded for providing high accuracy and dynamism of object center-of-mass motion control: elimination of object course stabilization in the field of low frequencies and use of integrating properties of steering engine instead of error signal integrator. The first requirement is realized either by introduction of flexible link type separation filter or by elimination of course sensor from angle stabilization loop and by use of angle speed sensor signal. The second requirement of positional invariance is realized by introduction of positive inertial feedback in addition to position negative connection of steering engine. The simulation results are given by the example of project 11356 frigate control system, confirming the effectiveness of the proposed method.
