Embedded control system by complex multi-component object, which operate in the real physical time, is considered. It is shown, that during solving the aim task it is necessary to synchronize controllable components operation by means of soft optimization. The model of embedded soft synchronization, based on discrete Petri-Markov net conception, is worked out. In the proposed conception time intervals are described with discrete distribution. Analytical simulation of the system soft operation is divided onto two parts: estimation of time interval discrete distribution of parallel soft operation inside synchronized block, and estimation of pre-determined plan realization effectiveness. Effectiveness criterion estimation is based on modified relay-race distributed forfeit method, due to which relay-race analysis with random time intervals is substituted by analysis of the randomly emerged rigid schedules systems, that essentially simplifies analysis procedure. |
