Derivative minor loop type controller

摘要

A controller for controlling a controlled system in connection with detecting means which detects the output of the controlled system and feedbacks a corresponding detected signal to the controller. The controller comprises proportional amplifying means for amplifying the error between a reference input signal and the detected signal, proportional and/or integral amplifying means for proportionally amplifying and/or integrating the error between the output of the proportional amplifying means and another signal to provide the resulting output as manipulating signal to the controlled system and derivative amplifying means for differentiating and amplifying the detected signal to provide the resulting output as the other input signal to the proportional and/or integral amplifying means whereby the controlled system is controlled in an overshooting-free mode.
