He provides control loop optimization services and training to industrial companies worldwide and has more than 20 years of experience in process control, including seven years in power plants.

Only through proper troubleshooting and then solving the underlying problems can control loop performance be improved. Process design certainly plays a role in control loop performance, but ...

A control loop can be causing its own oscillation, or it could be affected by an interacting oscillation somewhere else in the process. A simple way to determine if the origin of the oscillation lies ...

The same analog sensors are also used for PID closed-loop control, but in a more complex strategy. In on-off, closed-loop control of room temperature, for example, a heat or cooling cycle is triggered ...

For example, a control loop has to run in automatic control mode, be stable and responsive, and reduce process variability. Each aspect of loop performance can be expressed as a metric.

Figure 2 The design flow highlights control loop creation step by step. Source: Monolithic Power Systems. Control loop design process and calculations. Step 1: Design inputs. Once the converter’s main ...

Customers often returned process controllers to us for repair, because the field operators could not adjust them correctly. For example, consider a gas pipeline that is to operate at 3000 psi. When ...

The CS series of process control modules give you PID loop control of any process without using a PLC. A variety of modules are offered that allow control of temperature, flow, and pressure; the ...

In my estimation, this combination of human-in-the-loop automation can automate anywhere from 40%-100% of the process done by traditional BPOs, depending on the complexity, while helping ensure ...
