Batch processes pose particular challenges for closed-loop control and optimization due to inherent process nonlinearity and non-self-regulation. At the same time there is a greater potential for increasing capacity in batch than in continuous processes. Solutions need to address the interrelationship between yield, capacity, quality, and repeatability.
The electric industry still has done very little other than paper studies to address the Aurora mitigation. DOD is working with two utilities to demonstrate the use of the Aurora hardware mitigation devices. The first utility has provided DOD with several dozen event reports to date.
August 19th, I spent a day with the NERC Critical Infrastructure Protection (CIP) Version 5 Drafting team working on one of the NERC CIP Standards. The focus was on boundary protection, not on the actual control system devices and serial communications which were explicitly excluded.
The highest value added products use batch operations. Batches can take days to complete and be worth millions of dollars. In many cases bad batches cannot be fixed downstream. Bad batches must be avoided. There are many techniques for making batches more repeatable and faster by better monitoring and control.
The 14th ICS Cyber Security Conference (www.icscybersecurityconference.com) will have 5 major themes: Actual ICS cyber incidents; ICS cyber security standards; ICS cyber security solutions; ICS cyber security demonstrations; and ICS policy issues. The Conference focuses on what has REALLY happened and what is being done that affects the CONTROL SYSTEMS.
August 12th, the Silicon Valley Leadership Group hosted the 2014 Silicon Valley Cyber Security Summit. The attendance was very high level with 2 US Senators, 2 US Representatives, senior leadership from McAfee, Symantec, RSA, etc. There was almost no ICS focus or discussions though there were discussions about the need for...
There is still a prevailing view that control system cyber security is not real and the cost of addressing it is not commensurate with the “benefits”. There have already been more than 350 actual control system cyber incidents.
All of us are conscious that international standards play an important role in the design and implementation of automation and control systems as these are the areas in which we are most closely aligned. However in addition to automation standards the IEC and ISO also develop a wide range of...
Los Alamos National Laboratory is helping the DOE develop advanced predictive computer models of nuclear reactor performance.
Software for auto tuning and adaptive control provide the opportunity to identify key loop dynamics besides providing a sound fundamental and automated basis for getting the best PID settings. Presented are uses of the knowledge gained and the setup of the automation system and testing/monitoring of PID performance to get...
