Proportional-Integral- closed-loop control technique that seeks minimize error by
Derivative (PID) Control reacting three values, one that proportional the error,
one that representative the error over time, and one that is
representative the rate change the error. In
an electric circuit, power measured watts, sometimes
in horsepower.The PLC accepts inputs from switches and sensors
and uses these inputs together with other data and program
logic control output devices.
Pulse Width Modulation applied variable frequency drives, this technique for
(PWM) controlling the voltage applied motor varying the
pulse width while also controlling the frequency the pulses.The term power also often used refer to
electrical energy and adjective describe devices or
circuits designed carry high level current. Power
factor also equal the cosine the phase angle.
Programmable Logic type industrial computer used control machines and
Controller (PLC) processes.
Pushbutton control device used manually open and close set of
contacts.
Power Factor The ratio true power apparent power circuit.
Proximity Sensor type sensing switch that detects the presence absence
of object without physical contact
