In the last installment, we were halfway through the compensator design for a buck converter. As a quick recap, when designing digital compensators, the true system gain is different from the derived ...

Application flexibility and cost concerns are creating a demand for intelligent power-supply designs that support soft configuration in production and external control. These advanced power supplies ...

Proportional-integral-derivative (PID) loops are often employed to minimize position error in motion control systems. Typically, they are implemented with floating ...

The tuning of proportional-integral-derivative (PID) control loops was an important change at HollyFrontier’s Navajo Refinery in Artesia, N.M. Its hands-on, “mandraulic” culture was no longer cutting ...

PID (proportional, integral, derivative) control has existed for decades and there are many tools available to help implement PID to tune process control systems, thereby making it generally easy to ...

Self-regulating systems with feedback loops, i.e., the routing back of the output of a system to its input, have existed since antiquity and have since become an integral part of modern technology.

I studied physics in college, and I’m always surprised how fundamental some of the concepts are. Take waves for example. You really wouldn’t expect the same underlying concept to be at work on surface ...

Machines and processes are controlled using many strategies, from simple ladder logic to custom algorithms for specialized process control, but proportional-integral-derivative (PID) is the most ...

The objective of this project was to implement a digital PID controller on an FPGA for a control application. The objective of this project was to implement a digital PID controller on an FPGA for a ...

How to define the performance criteria of a digital control feedback system, such as a PID control system. How to define the speed and resolution of the control DAC and the sense ADC by using the ...
