This paper deals with automatic steering of ships under the influence of disturbances from waves. The disturbance has been of two different types, a sinusoidal wave and a disturbance in the yaw rate. We have used both conventional state feedback regulators and adaptive regulators based on least square estimation and minimum variance control. In particular, we have investigated the behaviour of the
Membranpotentialen hos en cell härledes som en funktion av membranens selektiva permeabilitet och koncentrationsgradienter över membranen. Hodkin-Huxleys nervmodell introduceras och med hjälp av digital simulering visas att den inte kan beskriva en lågfrekvent fyrande nerv. Enkla moditiferingar med bibehållen tolkning av ekvationerna ger en mer realistisk modell. Den modifierade modellen analysera
A simple flight simulator has been built up, using an analog computer to simulate the aircraft dynamics. The dynamics model used, does not represent any particular aircraft. It is nevertheless representative of a large group of conventional aircraft. Simulations clearly show an increased ease in handling the flight simulator, if the pilot has flying experience. This indicates a similarity between
