PID Controller
Mechatronics & Robotics · Chemical Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: A control loop feedback mechanism that continuously calculates an error value as the difference between a desired setpoint and a measured process variable, and applies proportional, integral, and derivative corrections.
Example in context
“The PID controller adjusts the motor voltage to maintain the robot joint angle at the desired trajectory.”
“PID denetleyici, robot eklem açısını istenen yörüngede tutmak için motor voltajını ayarlar.”
Where engineers use it
Widely used in motion control for tuning servo drives, temperature control, and speed regulation. Engineers tune Kp, Ki, Kd gains to achieve desired response without instability or excessive overshoot.
Synonyms: three-term controller, proportional-integral-derivative controller
Antonyms: bang-bang control
In Chemical Engineering
A controller that computes its output from three terms acting on the error signal: one proportional to the current error, one integrating past error, and one responding to the rate of change of the error. Tuning these three actions determines the speed and stability of the response.
“After retuning the PID controller with a longer integral time, the flow settled smoothly instead of cycling around the target value.”
Practice: can you use “PID Controller” at work?
A technician must tune a PID controller for a DC motor position loop using Ziegler-Nichols method, observing the response to a step input and adjusting gains accordingly.
Show a model answer
“Tune the PID controller gains to minimize the steady-state error.”
