For a standard turbine fan such as the diagram shows here, a typical simulation would only include sections S1, R2 and S2. New research from the GUIde 6 Consortium is now showing that including R3 is important to the accuracy of the simulations. Courtesy: Shreyas Hegde/Duke University

A new “particle simulator” developed by MIT researchers improves robots’ abilities to mold materials into simulated target shapes and interact with solid objects and liquids. This could give robots a refined touch for industrial applications or for personal robotics— such as shaping clay or rolling sticky sushi rice. Courtesy: Massachusetts Institute of Technology (MIT)

Plug and model simulation tools for automation software development suites

Simulation, modeling, and virtual commissioning are becoming easier to apply on different levels in automation. Interfaces to third-party simulation tools may be built into your software development suite already.

Figure 1: Output control with a permissive is shown in this output PLC logic, typical for an actuator. Various addresses need to be in the correct state for the Z_Axis_Lower_SV output to energize. These can be manipulated by the programmer, or in the case of the HMI pushbutton, it can link to an HMI program running on the programming computer and be pressed. Courtesy: Automation Consulting

How simulation helps automation and controls

The controls often must be programmed for automated machinery and systems before hardware exists, but controls engineers can use simulations to test syntax, proper tag linking and addressing, and code functionality.

Simulation model helps robots navigate more like humans

MIT researchers have now devised a way to help robots navigate environments more like humans do by letting robots determine how to reach a goal by exploring the environment, observing other agents, and exploiting what they’ve learned before in similar situations.

Control system simulator teaches operators how to thwart hackers

Researchers at Georgia Institute of Technology (Georgia Tech) have developed a simulator to help operators of chemical processing plants better understand the security issues of industrial control systems (ICSs). Future versions are being planned to simulate electric power grids, treatment facilities, and other manufacturing facilities.
