Active Disturbance Rejection Control-implementation examples

Active Disturbance Rejection Control (ADRC) simulator for SISO and MIMO systems. Implementation examples.

Active Disturbance Rejection Control (ADRC) is considered as a new control paradigm. It is mainly characterized by:
i. It does not require a detailed mathematical model of the process to be controlled. The system order and its critical gain need to be known.
ii. Non-modelled dynamics as well as other uncertainties and external perturbations are combined in an extended state which is estimated by an extended state observer.
iii. The information in the extended state (called "total perturbation") is used to transform the real process into a nominal disturbance-free plant controlled by a simpler state feedback law.

These files are the implementation of linear ADRC for two nonlinear application examples: a Peltier thermoelectric module (SISO example) and a Continuous Stirred Tank Reactor (MIMO example).

These implementation examples are addressed in the tutorial: "Control por rechazo activo de perturbaciones: guía de diseño y aplicación" (Active disturbance rejection control: a guide for design and application) DOI: https://doi.org/10.4995/riai.2020.14058
