How to tune PID loops

Servo-motor applications and temperature-control applications often need training after the auto-tune.

A Control Design reader wrote to us: I often have difficulty tuning PID loops, especially for temperature control applications and servo-motor motion applications. If I use a temperature controller, the auto-tune built into the device often works well if I follow the manufacturer’s recommendations. However, if the temperature control or motion control is through a PLC or other advanced controller, it's often a long training process to find the optimum coefficients for the proportional, integral and derivative of the control loop.
