A smooth starter for a DC machine: a flatness based approach

This paper considers the development of a smooth "starter" for a DC motor based on a switch controlled DCto- DC power converter of the "buck" Fpe. The dynarnic feedback controlEer is based on a flatness and a suitable Σ-Δ A modulator impiementation of the average designed conrrollep: The scheme proposes a direcl regululion of the motor shaft speed. The effectiveness of the proposed controller wus verified by computer siniularions using the P-Spice circuit simulation program.
