The field of process control monitoring has gained significant progress over the last 20 years. Existing studies have almost exclusively been devoted to continuous-valued or continuum system. In reality, however, many systems or problems may take noncontinuum form or state, such as "stiction" vs "no stiction" in a control valve. Even for processes with continuum state, one may be interested in only the noncontinuum representation such as "good", "bad" vs "optimal" in control performance monitoring problem. There is therefore a need to consider both continuum and noncontinuum states in process control monitoring.

在过去的20年里，过程控制监测领域取得了重大进展。现有的研究几乎都集中在连续值或连续统系统上。然而，在现实中，许多系统或问题可能采取非连续的形式或状态，例如控制阀中的“静摩擦”与“无静摩擦”。即使对于连续状态的过程，在控制性能监控问题中，人们也可能只对“好”、“坏”和“最优”等非连续表示感兴趣。因此，有必要考虑连续和非连续状态的过程控制监测。
