21. Prosthetic Foot Control for Ground Adaptation
Sammanfattning : Wearers of prosthetic feet find walking on inclined ground difficult or uncomfortable. A major reason for this is a limitation in ankle motion in existing prostheses. LÄS MER
22. Parameter estimation and model based control design of drive train systems
Sammanfattning : The main control task in many speed-controlled drives is to eliminate or reduce the load speed error caused by the load torque disturbance and reduce oscillations as quickly as possible. This thesis addresses different aspects of identification and control of such resonant elastic systems. LÄS MER
23. Control and Communication with Signal-to-Noise Ratio Constraints
Sammanfattning : This thesis is about two problems in the intersection of communication and control theory. Their common feature is that they involve communication over an additive white noise channel with a signal-to-noise ratio (SNR) constraint. The first problem concerns the transmission of a real-valued signal from a partially observed Markov source. LÄS MER
24. On Robust Distributed Control of Transportation Networks
Sammanfattning : With the ever-growing traffic demands, the transportation networks are getting more and more congested. While expanding these networks with more roads is both costly and in many cities not even feasible, the rapid development of new sensing and communication techniques has made it possible to perform control of transportation networks in real-time.

25. Chlorophyll fluorescence as a biological feedback signal -for optimized plant growth conditions and stress diagnosis
Sammanfattning : The use of light emitting diodes (LEDs) instead of traditional high pressure sodium lamps, in greenhouses and indoor growing facilities, enables tuning and optimization of both light intensity and light spectrum. This opens for an energy saving potential not possible otherwise. LÄS MER
