In order to improve the characteristics of the system design process a new general methodology for the electronic system design was elaborated by means of the optimum control theory formulation. This approach generalizes the design process and generates an infinite number of the different design strategies that will be resolved in time optimum. The principal difference between this new method and previously elaborated methodology is the more general approach on the system parameters definition. The main equations for the system design process were elaborated. These equations include the special control functions that are introduced into consideration artificially to generalize the total design process. Numerical results demonstrate the efficiency and perspective of the proposed approach.
