The Internet of Everything Delivers Smart Manufacturing

The Internet of Everything (IoE) is here now. Today it is estimated that manufacturers generate 2 exabytes of information daily—resulting in more “big data” than any other industry or sector. And when you consider that only 4 percent of the devices on the manufacturing floor are actually connected to a network, we can expect to […]

Multivariable Control Performance: A Case for Model-less Control

Multivariable control is usually thought of as a product of the computer age, but multivariable control has always been an integral part of industrial process operation. Before the computer era, the operating team did multivariable control manually, by adjusting the available controllers and valves to keep related process variables within constraint limits and to improve […]

Piecewise Controller Design for Affine Fuzzy Systems

Abstract: This paper studies the problem of state feedback controller design for a class of nonlinear systems, which are described by continuous-time affine fuzzy systems. A convex piecewise affine controller design method is proposed based on a new dilated linear matrix inequality (LMI) characterization, where the system matrix is separated from Lyapunov matrix such that the […]

Training Effectiveness: The Importance of a Personal Touch

Training and learning new skills are topics that employees often communicate as things they want more of from their employers. Unfortunately, those are very general terms and can be applied in many ways. What exactly is training, and how can it be implemented? It is important to take a 360-degree approach to developing employees. Companies […]

Production Line and Machine Upgrades Improve Productivity and Efficiency

The manufacturing industry has a large number of production lines and machines with old programmable logic controllers (PLCs) and custom controls that could benefit from an upgrade to newer technology. Many control and automation systems in current use were installed well over 30 years ago and are past their projected product life. Automation has been […]

PD Plus Error-Dependent Integral Nonlinear Controllers for Robot Manipulators

Abstract: In framework of traditional PID controllers, there are only three parameters available to tune, as a result, performance of the resulting system is always limited. As for Cartesian regulation of robot manipulators with uncertain Jacobian matrix, a scheme of PID controllers with error-dependent integral action is proposed. Compare with traditional PID controllers, the error-dependent […]

The Industrial Sector is Uniquely Vulnerable to Cyberattack

Cybersecurity is a growing international concern. Global insurance market Lloyd’s of London’s Risk Index 2013 rated cybersecurity the number three top threat to the global economy in 2013, up from number 12 the previous year. With the rise of cybercrime, it is important for companies and organizations to understand their unique vulnerabilities to this type […]

Temperature Sensor Installation for Best Response and Accuracy

The installation of the sensor can introduce errors, noise, and dynamics causing poor measurement and control loop performance. Here we look at best practices to get the most out of the inherent capability of the sensor. My next post will provide guidance on the communication of the sensor signal to the control room to provide […]
