Tuning of PI Controller
Tuning of a PI controller means adjusting the Kp and Ki term to achieve the optimized controller output by minimizing error and avoid overshooting and oscillation. Their are some rules that follows for tuning a PI controller.
- Tuning controller involves adjusting Kp and Ki for optimal system control.
- Start with initial guesses for Kp and Ki.
- Set Ki value to ‘0’
- Gradually increase Kp to achieve a fast response without excessive overshoot.
- Introduce Ki and incrementally raise it to eliminate steady-state error.
- Continuously fine-tune Kp and Ki, considering their impact on overshoot, setting time and steady state error.
- Test the controller under various condition.
- Tuning is an iterative process, and optimal parameters may vary for different systems, requiring practice and experience to achieve stable and effective control.
Proportional Integral Controller – Control System
The proportional controller commonly known as PI controller is an essential part of the Industrial Automation and Control system. It is a closed-loop feedback control mechanism that aims to adjust the process variable by manipulating the variable based on the error between the setpoint and the process variable. It strikes a balance between quick response to deviations and long-term error elimination. Tuning the controller allows adjustment to meet the desired value.
