Styrning av missil med hjälp av multimodellering

This report investigates the possibility of simulating the cruising of a missile by using the program Matlab and SimuLink. Matlab is a mathematical package with a number of application areas, for instance statistics, signalling and control theory. SimuLink is an easy to-use program package for building models and for simulation of both linear and non-linear technical control systems. The report describes a method of building a number of linear models by using process identification and at each point in time choosing the right model. The report also discusses how the model division should be done in order to obtain as good control as possible. Many processes with realistic complexity cannot be described by simple linear models, and not either as SISO (SingleInput-SingleOutput) system. But some systems can be modelled as a series of linear models. This is called multimodelling of non-linear systems. (Less)
