The dynamic calculation of automatic control systems is one of the most complex stages of designing of such systems. New spectral method of calculations of non-stationary automatic control systems adopted for computer is designed. Wavelet transformations are using for digital processing of signals. These transformations are cognate with usual Furies transformations and have advantages for representations of functions in the spectral domain. The spectral technique of digital describing of signals and systems are discussed in the article. Algorithms of analyses of non-stationary determinate and stochastic control systems in the wavelet basis are obtained.
