| 摘 要： | 基于混合仿真系统的离散动态模型,分析了混合仿真系统稳定的判据.在一个典型的一阶电路中,推导了混合仿真系统无直流稳态误差的条件,并设计了使混合仿真结果与真实解一致的接口算法.分析了步长和接口延时对混合仿真结果相移的影响,推导了相移的近似表达式.仿真步长等于接口延时的2倍时相移最小.通过仿真比较了不同接口算法和积分算法的效果,并验证了理论分析得到的结论.

| Abstract: | The criterion of stability is studied based on the discrete dynamic model of hardware-in-the-loop simulation system.The condition for the system having no steady state direct current error is derived on a simple first-order circuit system,and an interface algorithm is designed.The proposed algorithm can make the result of the hardware-in-the-loop simulation consistent with the actual result.The influence of simulation step and interface delay on the phase shift of the result is studied.The approximate analy... |
