Plant design for deterministic control of STEMS and tale-springs
In this thesis, the limits of conventional linear actuators for long stroke applications are discussed, and tape-spring based actuators such as the STEM are introduced as an alternative solution. While the literature contains several assessments of self-deploying tape-springs, little exists in the …

Inclusion of input saturation in the design of dynamically operable plants
… operability reflects the quality with which a plant can be controlled using feedback, and is a function of both the design of the plant and its associated control system. A plant designed on the basis of steady-state considerations alone could exhibit poor dynamic characteristics, leading to a …
