  2. Integral windup - Wikipedia

    en.wikipedia.org/wiki/Integral_windup

    Within modern distributed control systems and programmable logic controllers, it is much easier to prevent integral windup by either limiting the controller output, limiting the integral to produce feasible output, [5] or by using external reset feedback, which is a means of feeding back the selected output to the integral circuit of all ...

  3. Control reversal - Wikipedia

    en.wikipedia.org/wiki/Control_reversal

    Control reversal is an adverse effect on the controllability of aircraft.The flight controls reverse themselves in a way that is not intuitive, so pilots may not be aware of the situation; to roll to the left, they have to push the control stick to the right, the opposite of the normal direction.

    Closeup of a touchpad on an Acer CB5-311 laptop Closeup of a touchpad on a MacBook 2015 laptop. A touchpad or trackpad is a type of pointing device.Its largest component is a tactile sensor: an electronic device with a flat surface, that detects the motion and position of a user's fingers, and translates them to 2D motion, to control a pointer in a graphical user interface on a computer screen.

  5. Pro Co RAT - Wikipedia

    en.wikipedia.org/wiki/Pro_Co_RAT

    The distortion stage is followed by a passive "reverse" tone filter and volume control. This circuit has remained almost entirely untouched throughout the manufacture of the RAT and RAT2. Other versions of the RAT are near identical to the RAT2 except for changes to the clipping diodes, different enclosures, or the addition of new controls.

  6. Relay logic - Wikipedia

    en.wikipedia.org/wiki/Relay_logic

    The relay logic circuit forms an electrical schematic diagram for the control of input and output devices. Relay logic diagrams represent the physical interconnection of devices. Each rung would have a unique identifying reference number and the individual wires on that rung would have wire numbers as a derivative of the rung number.

  9. Inverted pendulum - Wikipedia

    en.wikipedia.org/wiki/Inverted_pendulum

    The inverted pendulum is a classic problem in dynamics and control theory and is widely used as a benchmark for testing control algorithms (PID controllers, state-space representation, neural networks, fuzzy control, genetic algorithms, etc.). Variations on this problem include multiple links, allowing the motion of the cart to be commanded ...
