  2. 1. Fixed-Feedback SISO Adaptive Control

    Author : Magnus Nilsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Two-Degrees-of-Freedom Control; Feedforward Control; Adaptive Control;

    Abstract : Adaptive control is an attractive method to solve control problemssince the tedious task of identifying process behavior to find asuitable design for the controller is taken care of by the adaptivecontroller itself. It may be difficult, however, to guaranteerobustness (in the sense of desired disturbance attenuation andstability margins) for traditional adaptive schemes since theircorresponding loop gain is time varying.

  4. 2. On Feedforward Adaptation

    Author : Magnus Nilsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control; feedforward; adaptive;

    Abstract : Adaptation of a feedforward term in a two-degrees-of-freedom servo controller for single-input single-output systems is investigated in this thesis. The first part ofthe thesis gives a clarifying analysis of feedback-error learning in a linear and time-invariant framework. READ MORE

  5. 3. Route Optimized Energy Management of Plug-in Hybrid Electric Vehicles

    Author : Viktor Larsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Convex optimization; Pontryagin principle; Energy management; Dynamic Programming; Data clustering; Splines; Plug-in hybrid electric vehicles;

    Abstract : Plug-in hybrid electric vehicles have the potential to significantly reducethe oil dependence within the transportation sector. However, there willalways be some trips that exceed the electric driving range, meaning thatboth electric energy and fuel must be used. READ MORE

  6. 4. On Sensor Fusion Applied to Industrial Manipulators

    Author : Patrik Axelsson; Mikael Norrlöf; Fredrik Gustafsson; Anders Robertsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : One of the main tasks for an industrial robot is to move the end-effector in a predefined path with a specified velocity and acceleration. Different applications have different requirements of the performance. For some applications it is essential that the tracking error is extremely low, whereas other applications require a time optimal tracking. READ MORE

  7. 5. Design and Control Parameter Optimization of Soft Ankle Exoskeleton for People with Dropfoot and Excessive Inversion

    Author : Xiaochen Zhang; Elena Gutierrez-Farewik; Ruoli Wang; Susanne Palmcrantz; Shaoping Bai; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Assistive device; Biomechanics; Gait impairment; Movement augmentation; Assistiv enhet; Biomekanik; Gångnedsättning; Rörelseförstärkning; Teknisk mekanik; Engineering Mechanics;

    Abstract : Wearable robotics and exoskeletons have been explored for their efficacy in physical rehabilitation and for assistance in daily activities for people with motor disorders. The overall objective of this thesis is to design a powered soft exoskeleton for people with dropfoot and excessive inversion, commonly after a stroke, and to optimize the control parameters for each individual while considering different dimensions.
