v0.2 — Advanced analysis

Core:

• MIMO systems — TransferFunction and StateSpace for multiple inputs/outputs
• Transport delay — Pade approximation pade(T, n)
• Phase and gain margin — margin(G) returning $G_m$, $\phi_m$, $\omega_{gc}$, $\omega_{pc}$
• Root locus — rlocus(G) for root locus analysis
• Pole placement — place(A, B, poles) using Ackermann's algorithm

Algorithms:

• PID in state space — formulation with integrated Luenberger observer
• LQI — LQR with integral action for disturbance rejection

---

v0.3 — Advanced control

• MPC — Model Predictive Control with sliding horizon and state/input constraints
• Adaptive control — MRAC (Model Reference Adaptive Control) for plants with varying parameters
• Real-time reconfiguration — swap the control law without stopping the simulation
• Observers — ObserverAgent with Kalman filter and Luenberger observer

---

v0.4 — Distributed infrastructure

• OS semaphores — protect SharedMemoryTransport against race conditions in multi-process
• Cross-process lock-step barrier — deterministic synchronisation using multiprocessing.Barrier
• Distributed clock protocol — coordinate $t_k$ between agents on different machines
• Fault tolerance — agent keeps running with ZOH when its peer disconnects

---

v0.5 — Hardware

• Serial/UART — SerialHardwareInterface for microcontrollers (ESP32, STM32)
• OPC-UA — interface for PLCs and industrial SCADA systems
• FPGA/FPAA — low-latency interface for analogue-digital co-simulation
• ROS 2 bridge — ROSTransport for robotics integration

---

v1.0 — Graphical interface

• JSON netlist parser — load a block diagram from a JSON/YAML file
• REST API — FastAPI exposing the simulation engine as a service
• Web visual editor — React frontend with React Flow for drag-and-drop block diagrams
• Real-time scope — WebSocket for streaming simulation data to the browser

---

Long-term ideas

• Antifragility — algorithms that reconfigure and improve under perturbations
• Digital twins — continuous synchronisation between model and physical plant
• Compilation to C — export the control law to embedded C code
• Julia integration — bridge to high-performance ODE solvers
