Parametric and Nonparametric PID controller tuning method for integrating processes based on Magnitude Optimum

MATLAB's implementation of the MOMI tuning rule for 2-DOF PID controller parameters for the integrating processes.

The algorithms are presented in the Open Access paper: T. Kos, M. Huba, and D. Vrančić, “Parametric and Nonparametric PID Controller Tuning Method for Integrating Processes Based on Magnitude Optimum,” Applied Sciences, vol. 10, no. 17, p. 6012, Aug. 2020, doi: 10.3390/app10176012.  Available online: https://www.mdpi.com/2076-3417/10/17/6012/htm (accessed on 31 August 2020).

Installation

Implemented code was tested in MATLAB version 2018. No additional installation is needed. Just run one of the main scripts (*.m files in the root directory of the code).

Description of the main MATLAB scripts used in paper

• PIDb_ilustritative_example.m

This .m file performs PID_b controller tuning and the closed-loop tests for different reference weighting factor b values. Used in Section 2.3 of the paper.

• PIDb_examples_tests.m

This .m file performs PID_b controller tuning and the closed-loop tests for different process models. Used in Section 4.1 of the paper.

• PIDb_PI_comparison.m

This .m file performs PID_b and 2-DOF PI controllers tuning and the closed-loop comparison between controllers for different process models. Used in Section 4.2 of the paper.

• PIDf_PIDb_comparison.m

This .m file performs PID_b and PID_f controllers tuning and the comparison of the closed-loop test between controllers for different process models. Used in Section 4.3 of the paper.

• PIDf_PIDb_robustness.m

This .m file performs PID_b and PID_f controllers tuning and the robustness test. Used in Section 5 of the paper.

• PIDf_comparison_other.m

This .m file performs PID_f controllers tuning and the closed-loop tests comparison with other tuning methods for integrating processes. Used in Section 6 of the paper.

• ChAmp_test.m

This .m file performs test, plots and calculation of the PID_b and PID_f controllers parameters, for the real-time process (control system for Charge Amplifier drift removal). Used in Section 7 of the paper.
