摘要
迟滞问题是指系统的状态变化不仅与当前状态有关 ,还与系统的过去状态有关 .考虑了对固定迟滞问题进行定性仿真求解 ,通过分析该类问题的可离散化特性 ,将问题求解范围从连续时间转化到离散时间点上来考虑 .并改进了定性与定量相集成的仿真方法—— Q2算法 ,增加了反映延迟性质的过去约束 ,通过当前约束和过去约束在系统中传播定量信息 ,从而完成固定迟滞问题的定性仿真 .
Time-lag problem means that the system states are affected by both current states and past states. The qualitative simulation of the fixed time-lag problem is discussed in this article. Discretization of the problem is analyzed, which makes it possible for us to consider the problem on discrete time points. Based on the Q2 algorithm, past constraints are added to represent the latency. By propagating quantitative information in the system with past constraints and current constraints, qualitative simulation of fixed time-lag system can be realized.
