ABSTRACT:
Detection of a process state change includes, in each of a number of filters having differing time constants, generating an estimated average process state from observed samples of the process. A number of state change decisions are generated by comparing each of the number of estimated process states with a respective one of a number of threshold values. It is then decided that the process has changed state if any one or more of the state change decisions indicates that the process has changed state.
