Power plants–especially coal-fired boilers–pose a set of process control problems unparalleled in other industries. Rapid load ramps, continuous unit demand changes, variable fuel quality and process ...

Control loop performance-monitoring software can help to improve loop performance at electric power plants by automatically collecting data, assessing several aspects of loop performance, and ...

Every plant in the process industry most likely has several control loops that do not perform well. Although there are many factors that may negatively affect control loop performance, a few of these ...

Switching power supplies rely on feedback control loops to ensure that the required voltage and current are maintained under varying load conditions. Design of the feedback control loop influences ...

Loop analysis of analog and mixed-signal discontinuous systems, such as PLLs, delta-sigma converters, switched-capacitor filters, PWM amplifiers, and switch-mode power supplies, presents a unique ...

RS-232 was the PC serial communications standard for many years. Hardware and software support for this simple, yet effective, interface was included on every PC made until it was eventually replaced ...
