Abstract :
A method of constructing nonlinear characteristics from given describing functions data is proposed here. By this method the real and imaginary part of a given describing function (DF) can be separately realized by nonlinear characteristics which can be selected for control systems compensation. Also a method for synthesis of imaginary and polynomial type DF is proposed. The network for the construction of such nonlinearities and its use for compensation of a nonlinear system having limit cycles is also presented.
