The method comprises: S1, when a semi-physical simulation system is used for carrying out semi-physical simulation of a launch vehicle control system, a synchronization simulation system carries out mathematic simulation, output data of all links of semi-physical simulation and mathematic simulation are compared in real time, and the operation situation of the semi-physical simulation system is evaluated in real time based on the deviation situation of the output data to control operation or stopping of the simulation process; and S2, after testing, the output data of all links of semi-physical simulation and mathematical simulation during the whole period are analyzed to realize evaluation of the whole semi-physical simulation process. Therefore, real-time monitoring of the semi-physical simulation system can be realized; and reliability of the system can be improved.

Description

technical field [0001] The invention relates to the field of semi-physical simulation of a launch vehicle control system, in particular to a synchronous evaluation system and method for a semi-physical simulation of a launch vehicle control system. Background technique [0002] In the existing hardware-in-the-loop simulation system of the launch vehicle control system, a simulator is used to solve the link of the rocket body, and other links such as inertial groups, arrow machines and servo mechanisms are realized with real products. Usually, after the half-in-the-loop simulation test is completed, the test data and Mathematical simulation comparison to evaluate the effectiveness of hardware-in-the-loop simulation. Since the hardware-in-the-loop simulation is a closed-loop simulation, this method cannot detect abnormal data in each link of the hardware-in-the-loop simulation in real time, which makes it difficult to judge the problem node. The hardware-in-the-loop simulatio...

Problems solved by technology

Since the hardware-in-the-loop simulation is a closed-loop simulation, this method cannot detect abnormal data in each link of the hardware-in-the-loop simulation in real time, which makes it difficult to judge the problem node

The semi-physical simulation test equipment includes large-scale test equipment such as three-axis turntables and rocket engines. Data divergence cannot be detected in time during the test, which will cause damage to the test equipment. Problems such as "speeding" of the turntable may also pose a threat to the safety of test personnel.
