Analog controllers using digital stochastic logic

AbstrO£tStochastic logic is based on digital pro· cessing of a random pulse stream, where the informa~ tion is codified as the probability of a hlgh level in a finite sequence~ The probability of the pulse stream codifies a continuous time variable. Subsequently, this pulse stream can be digitally proeessed to perfonn analog operatiO'nL In this paper we propose a stochas· tic approach to the digital implementation of complex oontroDers. This is approach allows for the realiza.. tion of the contron"", and AID and DlA converters within a digital programmable device,leading to simple circuit implementations. A practical reali:mtion of a classical pm and nonlinear dissipative controllers for the series swithehing power resonant converter is presented.
