Abstract

The invention discloses a mixed time sequence synchronous control method in physical simulation, relating to the technical field of simulation control and solving the working difficulties of data interaction and coordination between the real-time physical simulation derivation and non-real-time simulation control in the prior art. The mixed time sequence synchronous control method comprises the following steps: utilizing the physical time sequence of a real-object system to reversely trigger a non-real-time simulation time sequence; and leading the system to realize time-sequence unification and data exchange on prototype interface equipment by establishing effective and synchronous management. Under the mixed time sequence synchronous control mechanism, a simulation system progressing according to self step size originally can be matched with the physical time sequence under a certain condition. As the mixed time sequence synchronous mechanism is applied in the physical simulation, the simulation system not only considers the requirement of the prototype system simulation for real-time property under the high-accuracy requirements, but also ensures that an effective support which is provided for network integration and data interaction by an advanced simulation system frame based on an HLA (high level architecture) is given full play, so that the flexibility and expandability of application of the physical simulation system are improved.

Description

technical field [0001] The invention relates to the field of simulation technology, in particular to a system synchronization control method under real-time and non-real-time mixed control sequence. Background technique [0002] The hardware-in-the-loop simulation test system, as an important means of complex system research and development, performance test and index detection, has been paid more and more attention. Semi-physical simulation test is a kind of test method that is directly participated by real objects and combined with the application of simulation environment. Its system structure includes the following parts: simulation control system, environment simulation equipment and equipment under test. [0003] Determined by the working nature of the hardware-in-the-loop simulation system, its architecture generally needs to include two parts, real-time and non-real-time, the real-time part is used to complete real-time control and data collection of the environmenta...
