2. 1. Relay Feedback and Multivariable Control

   Author : Karl Henrik Johansson; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotics; Automation; Frequency methods; Process control; Sequential control; Automatic tuning; Control education; Laboratory process; Performance limitations; Decentralized control; Multivariable zero; Multivariable systems; Hybrid control; Nonlinear dynamics; Limit cycles; Oscillations; Relay feedback; Sliding modes; control engineering; Automatiska system; robotteknik; reglerteknik;

   Abstract : This doctoral thesis treats three issues in control engineering related to relay feedback and multivariable control systems. Linear systems with relay feedback is the first topic. Such systems are shown to exhibit several interesting behaviors. READ MORE

4. 2. Analysis and Design of Hybrid Control Systems

   Author : Jörgen Malmborg; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lyapunov theory; Mode switching; Multi-controllers; PID control; Simulation; Higher order sliding; Hybrid control; Sliding modes; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

   Abstract : Different aspects of hybrid control systems are treated: analysis, simulation, design and implementation. A systematic methodology using extended Lyapunov theory for design of hybrid systems is developed. The methodology is based on conventional control designs in separate regions together with a switching strategy. READ MORE

6. 4. Gear engagement control for transmissions in hybrid electric vehicles

   Author : Muddassar Piracha; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Noise and wear minimization; Dog Clutch; Hybrid Powertrain; Optimal control; LQI control; Mechanical Synchronizers; Dedicated Hybrid Transmission; Gear shifting; Drivability; Dual Clutch Transmission; Electric Powertrain; Phase plane analysis;

   Abstract : Hybrid and electric vehicles have become very important for vehicle manufacturers due to stricter legislation, government incentives and customers’ growing awareness of the environmental issues. For conventional vehicles, Dual clutch transmissions (DCT) have better shift quality and efficiency than conventional automatic transmissions. READ MORE

7. 5. Stochastic Event-Based Control and Estimation

   Author : Toivo Henningsson; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; event-based control; event-based estimation; sporadic control; stochastic control; stochastic hybrid systems; sum-of-squares methods; control over networks; quantized measurements;

   Abstract : Digital controllers are traditionally implemented using periodic sampling, computation, and actuation events. As more control systems are implemented to share limited network and CPU bandwidth with other tasks, it is becoming increasingly attractive to use some form of event-based control instead, where precious events are used only when needed.
