PI and PID controller tuning tool based on the lambda method

This paper presents a lambda tuner tool for the analysis and the design proportional-integral-derivative (PID) controllers using Matlab/Simulink software. The proposed application allows the user to easily obtain control parameters with lambda method and several traditional tuning methods. The lambda method guarantees robustness, stability and non-oscillatory response. It should be noted that the traditional tuning methods can't deal with such problem. The tuning methods use the plant model described by a first order system with delay. Also, step response and simulation of the control system designed are shown. Finally, the validation of the platform developed is tested with several simulations and an experimental test in a flow process using a Compact Logix PLC. The experimental results show that the proposed tool has a high performance.
