  1. CONTROLSDr. Konstantinos TsakalisArea Chair: Dr. Andreas SpaniasProfessor and Director NSF SenSIPI/UCRC

  2. Control Systems at ASU • EE Faculty: (Lai), Rodriguez, Si, Tsakalis • Topics: System Modeling, Control Systems Design, Neural Networks, Adaptive and Learning systems, Fault Detection, Real-time control applications • Applications: Aerospace (aircraft/missile control, optimal path planning) Semiconductor Manufacturing (process control, scheduling) Power Systems (generation, distribution) Biomedical applications (prosthetics, neuroscience)

  3. Control Systems Applications Control Systems: Use feedback to counteract the effects of uncertainty Early feedback control applications: Amplifiers, Telephony 60’s-70’s successes: Optimal and Multivariable Control, Rocket/Missile/Aircraft control Optimal path planning

  4. Control Systems Applications Cruise control “Launch” control Engine management Active Suspension ABS 80’s - 90’s themes: Sophisticated & reliable embedded control systems Simulation and Visualization Robotics Large-scale systems, Networks (Small and powerful computers, Cheap computations)

  5. Control Systems Applications High performance multivariable controllers designed from data. Reliable, with quick design turnaround time. Award-winning industrial controller • Philosophy and Expertise: • Control systems design and implementation • Modern multivariable modeling and control • Theory to experiment • Transferable technology, Systematic, Reliable • Integrated modeling and control • System identification, Uncertainty estimation, Controller design • Linear-Nonlinear methods, Feedback-Feedforward • Adaptive systems, Optimization • Embedded controller implementation • Controller performance and “health-status” monitoring • Applications: • Semiconductor Manufacturing (Semy/Brooks,Motorola,Intel) • Furnace temperature control, Run-to-Run, Scheduling • Process Control (Honeywell) • Paper machines, Petrochemical industry • Wastewater treatment using microbial fuel cells with peroxide production (SERDP, new) • Power Systems (EPRI) • Pulverizers, Power System Stabilizers • Biomedical (NSF, ERF) • Closed-Loop Control of Brain Dynamics in Epilepsy • Electromechanical, Embedded (CEINT-educational) We have developed a “feedback decoupling” control technology to design implantable brain stimulators that suppress seizures with high therapeutic efficacy and less side effects. Based on biologically plausible computer models of the brain.
