  2. Power take-off - Wikipedia

    en.wikipedia.org/wiki/Power_take-off

    Power take-off. A power take-off or power takeoff ( PTO) is one of several methods for taking power from a power source, such as a running engine, and transmitting it to an application such as an attached implement or separate machine. Most commonly, it is a splined drive shaft installed on a tractor or truck allowing implements with mating ...

  3. Proportional–integral–derivative controller - Wikipedia

    en.wikipedia.org/wiki/Proportional–integral...

    The distinguishing feature of the PID controller is the ability to use the three control terms of proportional, integral and derivative influence on the controller output to apply accurate and optimal control. The block diagram on the right shows the principles of how these terms are generated and applied.

  4. Electrical grid - Wikipedia

    en.wikipedia.org/wiki/Electrical_grid

    This diagram depicts the electrical structure [22] of the network, rather than its physical geography. Electric power transmission is the bulk movement of electrical energy from a generating site, via a web of interconnected lines, to an electrical substation , from which is connected to the distribution system.

  5. Servo control - Wikipedia

    en.wikipedia.org/wiki/Servo_control

    Servo and receiver connections A diagram showing typical PWM timing for a servomotor. Servo control is a method of controlling many types of RC/hobbyist servos by sending the servo a PWM (pulse-width modulation) signal, a series of repeating pulses of variable width where either the width of the pulse (most common modern hobby servos) or the duty cycle of a pulse train (less common today ...

  6. Proportional control - Wikipedia

    en.wikipedia.org/wiki/Proportional_control

    Proportional control, in engineering and process control, is a type of linear feedback control system in which a correction is applied to the controlled variable, and the size of the correction is proportional to the difference between the desired value ( setpoint, SP) and the measured value ( process variable, PV).

  7. Electrical wiring - Wikipedia

    en.wikipedia.org/wiki/Electrical_wiring

    Electrical wiring is an electrical installation of cabling and associated devices such as switches, distribution boards, sockets, and light fittings in a structure. Wiring is subject to safety standards for design and installation. Allowable wire and cable types and sizes are specified according to the circuit operating voltage and electric ...

  8. Circuit diagram - Wikipedia

    en.wikipedia.org/wiki/Circuit_diagram

    Circuit diagram. A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic ...

  9. Knob-and-tube wiring - Wikipedia

    en.wikipedia.org/wiki/Knob-and-tube_wiring

    v. t. e. Knob-and-tube wiring (sometimes abbreviated K&T) is an early standardized method of electrical wiring in buildings, in common use in North America from about 1880 to the 1930s. [ 1][ 2] It consisted of single-insulated copper conductors run within wall or ceiling cavities, passing through joist and stud drill-holes via protective ...
