Question:

For electromechanical systems that require large power amplification, rotary amplifiers are often used [8, 19]. An amplidyne is a power amplifying rotary amplifier. An amplidyne and a servomotor are shown in Figure P2.11. Obtain the transfer function Î¸(s)/Vc(s), and draw the block diagram of the system. Assume vd = k2iq and vq = k1id.
