2. CODESYS - Wikipedia

   en.wikipedia.org/wiki/CODESYS

   The Raspberry Pi interfaces, such as I²C, SPI and 1-Wire are supported in addition to the Ethernet-based field buses. Furthermore, SoftPLC systems under Windows and Linux are available, which turn industrial PCs and other standard device platforms from different manufacturers such as Janztec, WAGO , Siemens or Phoenix Contact into CODESYS ...

3. Servo drive - Wikipedia

   en.wikipedia.org/wiki/Servo_drive

   A servo drive receives a command signal from a control system, amplifies the signal, and transmits electric current to a servo motor in order to produce motion proportional to the command signal. Typically, the command signal represents a desired velocity, but can also represent a desired torque or position.

4. 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 ...

5. Proportional–integral–derivative controller - Wikipedia

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

   Tuning a control loop is the adjustment of its control parameters (proportional band/gain, integral gain/reset, derivative gain/rate) to the optimum values for the desired control response. Stability (no unbounded oscillation) is a basic requirement, but beyond that, different systems have different behavior, different applications have ...

6. Programmable logic controller - Wikipedia

   en.wikipedia.org/wiki/Programmable_logic_controller

   A PLC is an industrial microprocessor-based controller with programmable memory used to store program instructions and various functions. [21] It consists of: A processor unit (CPU) which interprets inputs, executes the control program stored in memory and sends output signals, A power supply unit which converts AC voltage to DC,

7. Servo (radio control) - Wikipedia

   en.wikipedia.org/wiki/Servo_(radio_control)

   The servo is controlled by three wires: ground, power, and control. The servo will move based on the pulses sent over the control wire, which set the angle of the actuator arm. The servo expects a pulse every 20 ms in order to gain correct information about the angle. The width of the servo pulse dictates the range of the servo's angular motion.
