This paper deals with the manual control of unstable systems, subject to control signal saturation. In particular we consider the Furuta pendulum, where the problem is to control the orientation of the arm manually while stabilizing the inverted pendulum. This paper presents an analysis which leads to an insight into the problem as well as the control strategy. This control strategy has been imple

Popular Abstract in Swedish Vattentransporten i växter är viktig för en mängd olika processer. De flesta fritidsodlare vet att vattentillgången påverkar växternas utveckling i stor utsträckning. För att solros ska kunna gro, växa, vända sig mot solen och bilda nya frön, behöver vatten flöda på ett kontrollerat sätt genom olika celltyper i växten. Växter transporterar vatten på olika sätt.
