PID 컨트롤러

A PID controller, or Proportional-Integral-Derivative controller, is a feedback control loop mechanism widely used in industrial control systems to maintain a desired output by adjusting process inputs. It combines three control strategies: proportional control responds to the current error, integral control addresses the accumulation of past errors, and derivative control predicts future errors based on the rate of change. This integration allows for precise and stable control of dynamic systems, enhancing product performance and reliability in various applications.
