Control apparatus for mechanical devices which regulates control system operation speed to prevent hunting and overshooting and thereby optimizes the control signal

摘要

A control apparatus for a mechanical device includes a control element for receiving a reference input signal and supplying an operating signal to the mechanical device, a main feedback element for detecting the control signal and supplying the detected control signal to the control element, and an auxiliary feedback element for detecting the operating signal to be supplied to the mechanical element and supplying the detected operating signal to the control element. The control element produces the operating signal based on the reference input signal, the control signal supplied from the main feedback element, and the operating signal supplied from the auxiliary feedback element to regulate the control speed such that hunting in the control apparatus does not occur.
