ABSTRACT:
A method of synthesizing a system which forces a finite value of an impedance to zero comprising positive current feedback of exactly specified nature and value of its transfer function and an internal negative voltage feedback ensuring inherent stability of the system. The converter is used to synthesize electric motor drive systems, incorporating any kind of motor, of infinite disturbance rejection ratio and zero-order dynamics and without position and velocity feedback.
