FAA controller staffing has been relatively flat in recent years - despite significant hiring - and is down 10% from 2012 because of retirements and trainees failing to complete requirements.

I was nursing a lukewarm vending machine coffee recently when I overheard two fresh-faced engineers complaining about the PID tuning process and coming up with ways to tear down centuries of control ...

Thus, you can’t use it as the feedback signal in the current-mode controller shown in Figure 1, and you will have to modify the controller to accommodate this new feedback signal. In this power tip, I ...

The demand for efficient and precise control of Brushless Direct Current (BLDC) motors has grown significantly in various industrial applications. Proportional-Integral-Derivative (PID) controllers ...

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 ...

Systems that exhibit oscillatory behaviours are commonly encountered in practice. The stabilization and good control performance of highly oscillatory systems are difficult to achieve using the single ...

With the integration of Boolean logic and regulatory control, the precision of the DCS in the execution of strategies and virtually no limit to functionality (for example the implementation of ...
