PID loops are a central component of modulating boiler control systems with applications ranging from basic steam header pressure control to cascading 3-element drum level control. A modern ...

For those new to fields like robotics or aerospace, it can seem at first glance that a problem like moving a robot arm or flying an RC airplane might be simple problems to solve. It turns out, however ...

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.

A few weeks ago, I installed an automatic water heater switch to my bathroom, but it was a crude device. What I really want to do is design a universal heater driver. That basic idea can be adapted to ...

The ABCs of PID control. Considerations for interfacing elements in the electrical circuit to accomplish those parts of the PID function for position control. Firmware code implementation.

Simulation of process control can ensure productive automation projects. But how much effort should be allocated to ...

A shift to angular and polar coordinates offers control engineers a more physically rigorous, PID-friendly approach ...

The RIO-47300 pocket PLC is an intelligent I/O controller that uses a RISC processor for handling I/O and logic. The RIO handles up to 400 program lines, 254 variables, 1,000 array elements, six PID ...
