This Matlab App allows the automatic computation of the nominal value of the critical gain, the controller bandwidth, and the observer bandwidth of the second-order LADRC for the control of a system approximated by a FOPDT model.

It requires as inputs the FOPDT model and through interaction with robustness level and manual tuning sliders, the user can visualize the closed loop response and evaluate the second-order LADRC performance with the aid of some measures.

This Tuning App computes the LADRC parameters by means of the tuning rules presented in the article: Tuning Rules for Active Disturbance Rejection Controllers via Multiobjective Optimization—A Guide for Parameters Computation Based on Robustness. DOI:

It contains its own built-in help and it was developed by using the MATLAB APP Designer.
