Abstract

The basic aim of this paper is to present a new controller circuit comprising a commercially available current-mode active component. This active element is called as current-feedback amplifier (CFA) and exhibits excellent properties compared to their voltage-mode counterparts, op-amps. The active element used in this work is AD844 from Analog Devices. The use of this active Component yields simple implementations and faster controllers. The proposed PID circuit is applied to a third-order attitude control system to verify the given specifications.
