Abstract :
The linearization of a switching system including a feedforward compensation for power supply perturbations is obtained by the addition of a high-frequency signal. A general expression for the required shape and amplitude of this high-frequency signal is derived. The method is analyzed for its application to AC phase control systems. The method is outlined for the case of a DC electric motor phase control. It is then generalized to any nonlinear switching system
