Data-Driven Control Toolbox
A companion MATLAB/Simulink toolbox implementing every methodology in Ali Khaki-Sedigh’s An Introduction to Data-Driven Control Systems (Wiley, 2024) — so each technique has directly runnable, tested code mapped to the corresponding book chapter.
Problem. Concepts like the Fundamental Lemma, data-enabled predictive control, model-free dynamic linearization, and unfalsified switching are intellectually clear but notoriously fiddly to get right in code: Hankel-matrix construction, persistency-of-excitation conditions, candidate-bank cost functions, and online estimation all hide subtle bugs. Students and researchers needed an implementation they could trust as a reference, usable both interactively and inside Simulink.
Approach. The toolbox is built as a MATLAB package namespace (ddc.*) with one category per chapter — ddc.common (Hankel matrices, persistency-of-excitation checks, sliding-window buffers, RLS, PRBS/multisine excitation), ddc.deepc (Data-Enabled Predictive Control), ddc.mfac (compact-form dynamic linearization), ddc.ufc (single- and multimodel unfalsified switching), ddc.spsa (Simultaneous Perturbation Stochastic Approximation), ddc.str (direct/indirect self-tuning regulator baselines), and ddc.vrft (Virtual Reference Feedback Tuning). Every stateful algorithm is a matlab.System class, so the same code runs both as a Simulink “MATLAB System” block and as a plain MATLAB object for offline simulation and scripting. A single consolidated library (ddc_lib.slx) registers one browsable “Data-Driven Control Toolbox” node in the Simulink Library Browser with category subsystem folders (Common Utilities, DeePC, MFAC, Unfalsified Switching, SPSA, STR Baselines). Everything ships with a self-contained matlab.unittest suite that needs no third-party toolboxes.
Outcome. The toolbox provides a complete, tested, chapter-mapped reference implementation of data-driven control — packaged as a distributable .mltbx via the Toolbox Packager API, documented with a contributing guide, code of conduct, and citation metadata, and installable either from the Add-On Explorer or directly from the repository.
