  2. Spinal cord stimulator - Wikipedia

    en.wikipedia.org/wiki/Spinal_cord_stimulator

    A spinal cord stimulator (SCS) or dorsal column stimulator (DCS) is a type of implantable neuromodulation device (sometimes called a "pain pacemaker") that is used to send electrical signals to select areas of the spinal cord (dorsal columns) for the treatment of certain pain conditions. SCS is a consideration for people who have a pain ...

  3. Industrial control system - Wikipedia

    en.wikipedia.org/wiki/Industrial_control_system

    Industrial control system. An industrial control system (ICS) is an electronic control system and associated instrumentation used for industrial process control. Control systems can range in size from a few modular panel-mounted controllers to large interconnected and interactive distributed control systems (DCSs) with many thousands of field ...

  4. Silicon controlled rectifier - Wikipedia

    en.wikipedia.org/wiki/Silicon_controlled_rectifier

    A silicon controlled rectifier or semiconductor controlled rectifier is a four-layer solid-state current -controlling device. The name "silicon controlled rectifier" is General Electric 's trade name for a type of thyristor. The principle of four-layer p–n–p–n switching was developed by Moll, Tanenbaum, Goldey, and Holonyak of Bell ...

  5. Feedback linearization - Wikipedia

    en.wikipedia.org/wiki/Feedback_linearization

    Feedback linearization is a common strategy employed in nonlinear control to control nonlinear systems. Feedback linearization techniques may be applied to nonlinear control systems of the form. where is the state, are the inputs. The approach involves transforming a nonlinear control system into an equivalent linear control system through a ...

  6. Proportional–integral–derivative controller - Wikipedia

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

    Proportional–integral–derivative controller. A proportional–integral–derivative controller (PID controller or three-term controller) is a control loop mechanism employing feedback that is widely used in industrial control systems and a variety of other applications requiring continuously modulated control.

  7. Distributed control system - Wikipedia

    en.wikipedia.org/wiki/Distributed_control_system

    e. A distributed control system (DCS) is a computerized control system for a process or plant usually with many control loops, in which autonomous controllers are distributed throughout the system, but there is no central operator supervisory control. This is in contrast to systems that use centralized controllers; either discrete controllers ...

  8. Instrumentation and control engineering - Wikipedia

    en.wikipedia.org/wiki/Instrumentation_and...

    Instrumentation and control engineering (ICE) is a branch of engineering that studies the measurement and control of process variables, and the design and implementation of systems that incorporate them. Process variables include pressure, temperature, humidity, flow, pH, force and speed. ICE combines two branches of engineering.

  9. Sliding mode control - Wikipedia

    en.wikipedia.org/wiki/Sliding_mode_control

    Sliding mode control. In control systems, sliding mode control (SMC) is a nonlinear control method that alters the dynamics of a nonlinear system by applying a discontinuous control signal (or more rigorously, a set-valued control signal) that forces the system to "slide" along a cross-section of the system's normal behavior.
