Using PID for motion control, robotics
Submitted by John Brokaw, Sr. Application Engineer at Valin for Control Engineering Magazine
Advice follows on using proportional-integral-derivative (PID) tuning for motion control and robotics. High-end robotics with high dynamics and reasonably high accuracy of movement almost always require the use of these control algorithms for operation.

Noise from Cavitation: Bad for Control Valves and Equipment
Submitted by Jon Monsen and Peter Jessee // Valve Magazine
Certain frequencies of sound can play havoc on industrial equipment. When control valves are not selected appropriately, there is an increased risk for cavitation, which causes high noise and vibration levels, resulting in very rapid damage to the valve's internals and/or the downstream piping.

Introducing the Cost-Effective SCARA Robot Pulse Motor IXP
Submitted by IAI
IAI's new IXP Series Robots cost around 1/2 of that of a conventional model due to the adoption of the pulse motors. The IXP achieves a payload equivalent to that of a conventional model by adopting high-output drivers. All IXP models come standard with battery-less absolute encoders.

Lower Running Costs by 1/3 with IAI Electric Actuators
Submitted by IAI
With air cylinders, a compressor is operated with electricity to generate compressed air, and generated air is supplied through a line to the air cylinder where it is then converted to linear-motion force. This mechanism is subject to significant energy loss.

How Gauges Can Help Prevent Costly Loss of Containment
Submitted by WIKA Instrument Guru
Loss of containment is one of the costliest things that can go wrong at a plant. Accordingly, smart enterprises employ a variety of measures that ensure loss of containment just doesn't happen or when it does, the adverse circumstances are kept to a minimum.
