Annotation
The subject is aimed to explanation of basic identification methods to obtain mathematical description of deterministic and stochastic systems. Experimental identification methods are explained for linear stochastic and deterministic dynamic systems in greater detail. Analytic identification is applied for several examples and compared to experimental identification. During this course the mathematical background of system identification in both time domain and frequency domain is given. Lectures are concentrated to the most frequent methods which are applied in practice. It is expected prior experience with Matlab.
