Abstract

The embodiment of the invention provides a continuous discrete hybrid system simulation propulsion method and device, equipment and a medium, and the method comprises the steps that for the simulationtime propulsion of a continuous system, the whole system propels the simulation time according to the minimum step length, and the time propulsion step length of a simulation object is an integral multiple of the minimum step length; and for discrete events, the events are divided into synchronous events and asynchronous events, the synchronous events are executed immediately after being generated, the asynchronous events are sorted in an event queue according to the sizes of timestamps, the asynchronous events are scheduled and executed when simulation time is advanced to the timestamps, andsimulation objects change the states of the simulation objects along with the advancement of the simulation time. According to the method, the advantages of time stepping and event advancing are integrated, the application range is widened, and the simulation advancing and scheduling efficiency is improved.

Description

technical field

[0001] The invention relates to the field of computer technology, in particular to a simulation propulsion method, device, equipment and medium of a continuous discrete hybrid system. Background technique

[0002] The efficiency of the simulation device operation is finally reflected in the speed of the simulation time advance, so how to increase the speed of advance is one of the key issues in the simulation. Currently, there are two basic propulsion mechanisms for the simulation device, the time-step-based propulsion mechanism and the event-based propulsion mechanism. The advancing mechanism based on time step calculates the state change of the device with the logic time as the variable. Each simulation advances the logic time by a fixed step, and calculates the latest state of the device according to this time step. The simulation step size is determined based on device and model characteristics prior to the run and is usually maintained throughout the si...
