Concept
Control theory is a field of study that focuses on the behavior of dynamical systems and the use of feedback to modify the behavior of these systems to achieve desired outcomes. It is widely applied in engineering and science to design systems that maintain stability and performance despite external disturbances and uncertainties.
Concept
A feedback loop is a system structure that causes output from one node to eventually influence input to that same node, creating a cycle of effects. It can be either positive, amplifying changes and driving growth, or negative, stabilizing the system by counteracting changes.
A Proportional-Integral-Derivative (PID) Controller is a control loop feedback mechanism widely used in industrial control systems to maintain a desired setpoint by minimizing the error between the setpoint and process variable. It combines three terms: proportional, integral, and derivative, each addressing different aspects of the control process to improve system stability and response time.
