Automation news and technical content from ISA
  • The post Estimation of Region of Attraction for Polynomial Nonlinear Systems first appeared on the ISA Interchange blog site. Abstract: This paper introduces a numerical method to estimate the region of attraction for polynomial nonlinear systems using sum of squares programming. This method computes a local Lyapunov function and an invariant set around a locally asymptotically stable equilibrium point. The invariant set is an estimation of the region of attraction for the equilibrium point. [...]

  • The post Industrial Automation and Embedded Vision: A Powerful Combination first appeared on the ISA Interchange blog site. In order for manufacturing robots and other industrial automation systems to meaningfully interact with the objects they are assembling, as well as to deftly and safely move about in their environments, they must be able to see and understand their surroundings. Cost-effective and capable vision processors, fed by depth-discerning image sensors and running robust software [...]

  • The post Listen, Celebrate, Recognize – The 2014 ISA Hall of Fame first appeared on the ISA Interchange blog site. Involve everyone in everything… “Wholesale involvement is necessary to engender the level of quality, service, and flexibility required by today’s markets. Intense communication is required to foster that involvement; we must: Listen constantly, congregate, or share ideas/information, and recognize achievement Celebrate –informally and formally–the “small wins” that are indicative of the solid day-to-day performance turned [...]

  • The post Mobile HMI Technology Enters a New Era first appeared on the ISA Interchange blog site. A significant shift is occurring in the automation world: the PC, while still an important element in the technology   mix, is no longer the dominant method for remotely accessing automation systems. This is the result of changes in technology and business practices. The Great Recession precluded many companies from hiring additional staff, making them do [...]

  • The post Global Adaptive Output Feedback Control for a Class of Nonlinear Time-Delay Systems first appeared on the ISA Interchange blog site. Abstract: This paper addresses the problem of global output feedback control for a class of nonlinear time-delay systems. The nonlinearities are dominated by a triangular form satisfying linear growth condition in the unmeasurable states with an unknown growth rate. With a change of coordinates, a linear-like controller is constructed, which avoids the repeated derivatives of [...]

  • The post Top 10 Differences Between ICS and IT Cybersecurity first appeared on the ISA Interchange blog site. In many, if not most plants with industrial control systems (ICS), ICS engineers and their internal information technology (IT) counterparts have very different perspectives on cybersecurity. Not surprisingly, these different perspectives often lead to conflicts when connecting an ICS to the plant’s IT system. In the past, because industrial control systems used proprietary hardware and [...]

  • The post Getting Concentration Measurements from Common Inline Sensors first appeared on the ISA Interchange blog site. Ultimately what we want to know and control is the concentration of key components. Relatively inexpensive inline measurements can be used under the right conditions to provide concentration measurements. Understanding the limitations as well as the capabilities is essential to success. Here we look at how we can elevate the use of capacitance, conductivity, density, [...]

  • The post Safety Analysis of Discrete Event Systems Using a Simplified Petri Net Controller first appeared on the ISA Interchange blog site. Abstract: This paper deals with the problem of forbidden states in discrete event systems based on Petri net models. So, a method is presented to prevent the system from entering these states by constructing a small number of generalized mutual exclusion constraints. This goal is achieved by solving three types of Integer Linear Programming problems. [...]

  • The post What Does a Successful Enterprise Asset Management Implementation Look Like? first appeared on the ISA Interchange blog site. Enterprise asset management (EAM) is a way of thinking, a discipline, and ultimately a culture that increases equipment life and production uptime. One of the dichotomies we face when we talk about asset life is the conflict between quality and reliability in the corporate world, and disposability in everyday life. When our new washing machine [...]
