半实物仿真是一种针对实际过程的实时仿真技术，它可将需要的实际受控对象放置在仿真

系统回路中进行仿真研究，可对控制参数进行在线调参，改善实际系统的性能-Loop simulation is an actual process for real-time simulation technology, it can be the actual controlled object will need to be placed in the loop simulation system for simulation, can control parameters on-line parameter adjustment to improve the performance of the actual system
