We would like to thank Michelle Barnes, Craig Hiemstra and Blake LeBaron for their helpful comments. The usual disclaimer applies.
Much of what is known about physiological systems has been learned using linear system theory. However, many biomedical signals are apparently random or aperiodic in time. Traditionally, the randomness in biological signals has been ascribed to noise or interactions between very large numbers of constituent components. One of the most important mathematical discoveries of the past few decades i...
Well-known Box-Jenkins Autoregressive integrated moving average (ARIMA) methodology has virtually dominated analysis of time-series data since 1930s. However, it is applicable to only those data that are either stationary or can be made so. Another limitation is that the resultant model is “Linear”. During the last two decades or so, the area of “Nonlinear time-series” is rapidly growing. Here,...
In this paper a robust controller using µ-synthesis method has been designed for attitude control system of a micro-satellite in LEO orbit. Then the controller has been evaluated with accurate linear and nonlinear simulations. After necessary evaluation three-axis stabilization method with only magnetic torques and auxiliary gravity gradient boom was been selected. Nonlinear kinematics and dyna...
