Controlling hydraulic motion with precision involves understanding the fundamental difference between servo motors and hydraulic actuators. Electric motors generally respond linearly to control inputs ...

PID (proportional, integral, derivative) control is not as complicated as it sounds. Follow these simple implementation steps for quick results. At work, I am one of three designated “servo guys,” and ...

A unified approach to advanced control can make utilizing the full power of PID less of an art and more of a documented, fast and straightforward procedure. This column, first in a series of “User ...

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.

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, ...
