ABSTRACT:
A high gain feedback control system is disclosed which is capable of stably operating without exhibiting any unstable phenomena such as natural frequency. The control system comprises a high gain controller, a controlled system, a detecting means and a summing point, and is constructed in a manner that the detecting function has a transfer function determined to allow a loop transfer function of the control system to have (n-1) zero points when the loop transfer function has n poles, to thereby permit the transfer characteristics to compensate for the transfer characteristics of the controlled system with a time lag. Also, a high gain multi-loop feedback control system is provided which is capable of exhibiting such advantages.
