    • Abstract:
      • Synthesis of sequential diagnostic tests is facilitated with a novel modeling strategy. • The dynamic behavior of any given system is modeled with untimed automata. • Both engineering knowledge and simulation data can be incorporated into a hybrid model. • The resulting diagnostic test plans are applicable in practical applications. • The validity of this approach has been demonstrated in examples concerning the startup operations. Although the automata based diagnostic tests have already been developed in the past for differentiating the originally inseparable fault origins in simple chemical processes, their applicability in realistic systems is still questionable. This is primarily due to the facts that automata are basically modeling tools for the discrete event systems (DESs) but most process variables are continuous. To address this practical issue, the dynamic behavior of every processing unit involved in a given operation is modeled in this work by incorporating both the generic engineering knowledge and also the ASPEN-generated dynamic simulation data into a single automaton. The improved test plans can then be synthesized according to the system model obtained by assembling all such automata. The feasibility of this automata based model building strategy is demonstrated with two examples concerning the startup operations of a flash process and also a distillation column.
