摘要
若混合系统的连续部分存在定时器 ,则无法应用基于阈值切换面划分的验证方法。为此 ,首次提出了综合流管道近似和阈值切换面划分的方法以及过渡状态的概念。在流管道近似过渡状态集合时 ,扩大其在时间上的分析范围 ,便可自动得到定时器的合理设定范围。最后通过实例验证了上述方法的可行性 。
A method of integrating Partition of Threshold Switching Surfaces (PTSS) and Segmenting Approximation of Flow Pipe (SAFP) is proposed to solve the problem that PTSS is not applicable if there exist timers in continuous blocks, and the notion of interim states is put forward. Enlarging the analysis time domain when interim states are approximated by SAFP, the timer′s reasonable range can be got, which expands the application scope of the method. An example of chemical process control shows that the method is effective and superior to the simulation method.
