  2. Robust embedded control systemsin ELECTA • robust embedded control systems • one of major ELECTA research pillars • besides distributed generation, power electronics, energy markets, high voltage, numerical EM modeling • 3 ZAP, 6 postdoc, 35 PhD, 5 ATP • R.Belmans, G.Deconinck, J.Driesen, D.Van Dommelen • http://www.esat.kuleuven.ac.be/electa • applications / platforms / methodology • fundamental and applied research • GOA, FWO, SBO, GBOU, … • EU-FP5, EU-FP6, IWT, … • companies & research institutes • co-founder energy institute Geert.Deconinck@esat.kuleuven.ac.be

  3. ELECTA application example:Controlling microgrids with inverter front-ends • electricity network remains stable • also when disconnected from mains (islanding) • based on renewables (wind, solar), storage and load management • voltage and frequency droop control Geert.Deconinck@esat.kuleuven.ac.be

  4. ELECTA application examples:Intelligent drives & motor control • sensor and sensorless control • extended Kalman filter, neural networks, … • DSP-based controllers • high performance motion control of AC drives • drive DC bus voltage control during power interruptions • 4-quadrant control of switched reluctance motor • … Geert.Deconinck@esat.kuleuven.ac.be

  5. ELECTA application example:Distributed control systems electricity network substation communication network dispersed generation intelligent meter • optimising power quality, energy cost, loss, … • based on robust ICT infrastructure • fault-tolerant middleware • redundancy in heterogeneous networks • serial wire / wireless / power line communication • in dynamic environment • resource discovery • overlay networks Geert.Deconinck@esat.kuleuven.ac.be

  6. ELECTA platform example:Rapid prototyping of control systems • different measurements algo’s •  power quality definitions • different control actions • active filtering • distributed systems • optimisation based on marginal costs DSP + FPGA / processing measurement / acquisition host / monitoring / communication inverter / actuator Geert.Deconinck@esat.kuleuven.ac.be

  7. Electa platform example:distributed real-time systems • RT network • with embedded hardware • Single Board Computers & (industrial) PCs • microcontrollers, DSP’s, FPGA’s, … • real-time & general purpose OS • QNX, WinCE, VxWorks, RMOS32, Linux, WinNT, … • TCP/IP stack & dedicated communication libraries • middleware, providing support for • fault tolerance, quality-of-service, real-time aspects Geert.Deconinck@esat.kuleuven.ac.be

  8. ELECTA methodology example:design of dependable real-time systems • explicit fault and failure models of ICT infrastructure • dependability modeling • reliability, safety, … • fault prevention, ~tolerance, ~removal, ~prediction • instantiation of modular middleware architecture • dependable communication & computation • in dynamic environments • assessment of dependability, time & cost constraints • conceptual evaluation and fault injection • interdependencies on other critical infrastructures • energy, telecom, information & fault propagation Geert.Deconinck@esat.kuleuven.ac.be
