  • Phase 1: Simulink Basics → Phase 2: Classical Control → Phase 3: Modern Control
  • Phase 4: Advanced Control → Phase 5: Applications & Deployment
• Reorganized run_all_tutorials.m and t00_main_guide.m to follow learning path
• Updated README (中文/English) with new Phase tables, learning path diagram, and FAQ

Fixed

• t23: Completed MIT adaptive law wiring (was marked TODO)

• t25: Updated Simscape block paths for R2025a compatibility
• t21/t17/t24: Fixed dual-controller Plant block conflicts
• All save_system paths now use absolute paths (t22-t25)

[1.2.0] - 2026-07-18

Added

• Star History chart in README (中文/English)
• GitHub Actions CI workflow: syntax check, structure validation, monthly schedule
• CI passing badge in README

Changed

[1.1.0] - 2026-07-17

Added

• 6 advanced control tutorials: t16 (frequency domain), t17 (lead-lag), t18 (system ID), t19 (H∞ robust), t20 (MPC), t21 (sliding mode)
• GitHub community health files: issue templates (bug, feature, tutorial request), PR template
• CODE_OF_CONDUCT.md and SECURITY.md
• FUNDING.yml

Changed

• Total tutorials: 15 → 21
• README overhaul: added table of contents, quick start, prerequisites, collapsible sections, improved badges
• README_EN.md synced with latest structure
• Updated CONTRIBUTING.md with detailed guidelines

Fixed

• t19 LQR state feedback closed-loop formula (line 138): replaced incorrect feedback() with proper A-BK formulation
• t19 fig3 layout: changed from 1×2 to clean 2×1, removed empty axes

[1.0.0] - 2026-07-17

Added

• 15 Simulink tutorials covering fundamentals, control theory, and mechatronic systems
• 14 .slx Simulink model files
• run_all_tutorials.m — one-click batch runner
• Simulation result figures in docs/images/
• English README (README_EN.md)
• Contributing guidelines (CONTRIBUTING.md)
• MIT License

Tutorials

• Phase 1 (t01-t08): Signal basics, math blocks, first/second-order systems, PID control, sources/sinks, subsystems, masking
• Phase 2 (t09-t12): State-space models, LQR optimal control, Luenberger observer, Kalman filter
• Phase 3 (t13-t15): DC motor modeling, PMSM FOC vector control, embedded C code generation

v1.1.1 — Star-Project Overhaul

• t21 — Sliding Mode Control: nonlinear robust control, chattering suppression

📖 Documentation Overhaul

• Bilingual README (中文 + English) with table of contents, quick start,
  prerequisites
• Collapsible tutorial details with learning path diagram
• Updated Simulink学习笔记.html covering all 21 lessons
• Academic CITATION.cff for easy referencing

🏗️ Project Structure

• .slx models moved to models/ — root directory now clean
• utils/getSimData.m — consolidated 6 duplicate functions into one shared utility
• GitHub community files: issue templates (bug/feature/tutorial request), PR template
• CODE_OF_CONDUCT.md, SECURITY.md, FUNDING.yml, dependabot.yml

🐛 Bug Fixes

• t19: LQR state feedback now uses correct A-BK closed-loop formula
• t19: H∞ visualization overhaul — envelope shading, DC-gain compensation,
  constraint violation highlighting
• t04: Fix broken Unicode escape (\x03B6 → ζ) causing garbled output
• t20: Guard quadprog/optimoptions with exist() for users without
  Optimization Toolbox
• t19, t20, t21: Wrap toolbox-dependent functions (ureal, hinfsyn, rms) in
  try-catch for graceful fallback
• t21, t13: Guard find() against empty results in convergence checks
• t16: Store and display gain/phase margin results (were previously discarded)
• t15: Fix incorrect "series complete" message (t16-t21 exist)
• t08: Correct outdated comment referencing Simscape
• t18: Remove dead no-op code
• t20: Remove dead A_pow computation loop
