Bang-Bang Control
Bang-bang control, also known as on-off control, is a simple feedback control strategy where the controller output switches abruptly between two fixed states (typically 'on' and 'off') based on whether the system error exceeds a threshold. It is commonly used in systems where precise continuous control is not required, such as thermostats or simple motor controllers. This approach is computationally inexpensive and easy to implement but can lead to oscillations and wear due to frequent switching.
Developers should learn bang-bang control when working on embedded systems, robotics, or automation projects that require basic regulation without complex algorithms, such as temperature control in HVAC systems or simple position control in actuators. It is particularly useful in resource-constrained environments where minimal processing power is available, but it is not suitable for applications needing smooth or precise control, like high-performance servo systems.
