INTERVAL LOGIC FOR PROCESS CONTROL SYSTEM SPECIFICATION
P.P.K. Chiu, Ying Shan Cheung · Journal of Circuits Systems and Computers · 1991
A new methodology for the specification of process control systems involving time interval information and verification of their design is proposed. The specification is based on interval logic and a time-interval operator is defined. By means of this operator, time interval information is incorporated in the specification. Thus properties that involve time intervals can be verified. Moreover, combinational and sequential processes can be specified. An application example for a process control system is demonstrated.
