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 ...

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 ...

It is a common situation in electronics to have a control loop, that is some sort of feedback that drives the input to a system such as a motor or a heater based upon a sensor to measure something ...

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 worker is about to enter a confined space. Prior to entry, he reaches down to his belt and pulls out his gas monitoring device. He points the device into the confined space and initiates a scan of ...
