Design of a simple setpoint filter for minimizing overshoot for low order processes

Area of Science:

• Control Systems Engineering
• Automation Technology

Background:

• Setpoint filters are crucial for PID controllers to manage system responses.
• Existing methods for designing setpoint filters are often complex and require detailed system information.

Purpose of the Study:

• To develop a simplified method for designing setpoint filters.
• To reduce peak overshoot in system responses to a tolerable level.

Main Methods:

• A novel, calculation-light method for designing setpoint filters is proposed.
• The method utilizes only the peak overshoot and peak time of the system response.
• It is independent of system type, order, and PID controller parameters.

Main Results:

• The proposed method effectively reduces peak overshoot.
• Demonstrated efficacy across various system examples.
• Significantly simpler than existing laborious filter design techniques.

Conclusions:

• The developed setpoint filter design is simple and effective.
• It offers a practical alternative to complex existing methods for PID control.
• This approach facilitates easier tuning and improved system performance.
