The control of industrial processes is set up in a hierarchial                  mode.  At the bottom are the regulators which handle short term,                random, rapid fluctuations, in the middle are control actions to                maintain stability in response to changes in set point, feed,                   etc., and above all this is long term, production planning, etc.                The PI's work falls in the middle of the control hierarchy:  he                 plans to develop a high-level surveillance and corrective system                that can sustain control system and process operability when                    abnormal situation arise.                                                                                                                                       There are hundreds of feedback/feedforward control loops in a                   process plant that are supposed to function in concert, yet                     reports of practicing engineers over the years claim that half of               them are out of commission at any one time reason or another.                   Malfunction of control system components, human operator                        decisions and actions, unusual process conditions, and control                  system design deficiencies are some of the reasons.  The focus of               this work is to synthesize and develop a surveillance system                    capable of assessing the operational status of multiloop control                systems and the integrity of operation of the process they                      control in continually changing, such a surveillance system will                need redetermine the current structure each time a change in                    status is detected.  Status changes can occur owing to failure of               sensors, failure of actuators, unrelieved saturation of process                 manipulatable inputs, breaking of signal continuity in multilevel               cascade systems, and operators, unrelieved saturation of process                manipulatable inputs, breaking a signal continuity in multilevel                cascade systems, and operator actions.  The system will                         incorporate the following components:                                                                                                                                1.   Determination of the current control system                                     structure.                                                                                                                                                 2.   Identification of the changes that have occurred.                                                                                                          3.   Assessment of prospective control system                                        modifications needed to address the exigencies of                               the moment.                                                                                                                                                4.   Development of a procedure for implementing the                                 structural changes in a coordinated and safe                                    manner.
