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 ...

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.

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 ...

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.

The PAX2C from Red Lion Controls features new Ramp Soak capabilities and FlexCard plug-in options that enable users to reduce costs by easily changing or adding functionality to meet industrial ...

The reactive controls we discussed in Part 1 are driven entirely by error. This is a bit like driving a car while looking out the back window. Your mistakes may be ...

Any good athlete will tell you that the key to an exceptional performance is to imagine the task ahead and then to practice until the body can bring this imagined sequence into reality. Similarly, ...
