… a multivariable control method. One problem is that the engine system is non-linear. Furthermore there are strong cross-connections between inputs and outputs and the inputs have alsoboundaries. To be able to manage these control problems, MPC has been used that is a …
… diagnosis two models were developed for two different engine parameters, one linear state space model and a neural network. These two models are then used to isolate the faults. The linear state space model is used to estimate the temperature right behind the engine turbines …
… tidigare studier har det visat sig att den moderna slutfasstyrningsalgoritmen Linear Quadratic Augmented Proportional Navigation (LQAPN), som återkopplar missilens acceleration och rotation, uppvisar en bättre prestanda än de mer klassiska styrlagarna. Det främsta intresset med …
… input data in a higher dimensional space, the feature space, in which linear operations on the data can be processed more easily. These operations in the feature space can be expressed in terms of input data thanks to the kernel functions. Support Vector Machines is a classifier …
… the filtering calculations. Examples of such functions are routines for linearization and integration. To decrease the time-consumption, we have also developed a routine to make it possible to convert a simulink model to a state-space description. This conversion makes it …
… the dependent variable of economic development. The test is carried out by a linear regression analysis. The analysis shows not only that there is a significant positive relation between state and economic development but furthermore that the relation between the variables is …
Klingande gestaltning av pianostycken i romantisk stil utifrån instuderingar med reducerade notbilder
… the original ” can stimulate a more artistic interpretation as well as a more linear understanding of the piece. My analysis also investigates what kind of impact these kinds of scores have on memorization. The music is derived from the romantic piano repertoire and the subjects …
In modern industrial robots the components in the transmission contain nonlinearities. These nonlinearities need to be to estimated either for better control or to use the parameters for diagnosis of the system. There is a lot of work done within system identification and mainly …
En studie av överutnyttjandet av tillfällig föräldrapenning vid införandet av en karensdag i det svenska sjuklönesystemet
… because of the higher gain from the welfare system. We use OLS to perform a linear regression from a data set from the data base LINDA during 1991-1996. The results in this paper are that there is a significant increase in the parental benefit after the reform although there is …
… were examined and a model was created in ANSYS using PIPE20 elements with linear ? elastic material model. This model was, when compared to the analytically expected results, very accurate and could thereby be used in further analysis. A short study of the PIPE20 element was …
En studie av kameraaktiveringens effekter på fordonshastigheter i Sverige
… differ, we used two different response variables in the analysis. Multiple linear regression was used to analyse the average speed, while Poisson regression was used in the analysis of the number of speed violations. An activated camera proved to cause a lowered average speed …
… soil seed banks revealed a maximum density of 2200 seeds /m2 to 10 cm depth. A linear regression showed that the size of the seed bank was negatively related to wave exposure (F1,3= 36,71 P=0,009, R2=0,96). In August, the depth distribution of the plants was described in 5 …
… of supply and demand theory. The empirical study is implemented by the simple linear regression model and a vector autoregressive model (VAR). Empirical foundation: Based on the theoretical frame of reference, the link between the time series is examined by using selected …
… inom regressionsanalysen som kallas Styckvis Linjär Regression eller Piecewise Linear Regression.
… vary depending on, for example, speed and position. Hence, a time-invariant linear model cannot describe its properties under all flight conditions. It is therefore desirable to update the linear helicopter model continuously during the flight. In this thesis, two different …
