PID & Alternate Control System

Published under Control System

PID (Proportional-Integral-Derivative) controller is control loop feedback mechanism that widely used in control system. PID calculating the error value that generated by difference between feedback Process Value (PV) and Set Point (SP) PID. When error value generating, PID controller adjusting output Measurement Value (MV) to minimize error near to zero value. Let us give some [...]
