The coupling coefficient perturbation method and the simulation stepsize perturbation method are established. For two classes of systems of test equations, we construct the parallel simulation models and prove that they have the stability behaviour which is similar to the original continuous systems.展开更多

The idea of computation of the analogue computer is intro-duced into the computation of digital simulation, the system is decomposed into somesubsystems, each of which can run independently, and, with the input informations ap-proached to, the local analytical expressions for the solutions of these subsystems are cons-tructed. Finally, a simple analysis about the accuracy estimate and the stability of the algo-rithms are given. The computational results show that the CPU time expended on thedigital simulation of a flying control system is only 1/20 of that needed by the traditionalnumerical methods.展开更多
