Industrial Pervasive Sensing Reduces Costs and Prevents Downtime

There has never been a greater need for plant reliability and energy efficiency. Both depend upon actionable information: plant operators need to know what is happening everywhere in the plant, often in close to real time. This was seldom done in the past, mainly for cost reasons. However, the availability of innovative sensors (many of […]

Webinar Recording: Model-Predictive Controllers for Cost Optimization

Having two small model-predictive controllers (MPCs) available as a standard option in a distributed control system (DCS) shows much better performance than the previous PID for product pH and assay control, reducing off-spec product and raw material use. The MPC effectively deals with a recycle stream and a level override scheme that can change production […]

DC Servomechanism Parameter Identification: Closed-Loop Approach

  Abstract: This paper presents a Closed Loop Input Error (CLIE) approach for on-line parametric estimation of a continuous-time model of a DC servomechanism functioning in closed loop. A standard Proportional Derivative (PD) position controller stabilizes the loop without requiring knowledge on the servomechanism parameters. The analysis of the identification algorithm takes into account the control […]

ISA Needs to Change, but How?

As you’ll recall, I stated in my February post that ISA’s long-term value and success depend on our ability to embrace change and become:  more flexible, more adaptable, faster to market, and less reactive. So how do we move ahead and work to achieve these change goals? First of all, driving organizational changes begins at […]
