Description: |
| Abstract:
A position-controlling system associated with one or more movable members and utilizing a resolver type inductive coupling device such as a "linear Inductosyn," characterized by the transmission of alternating voltages having more than one frequency through the device. In the preferred form, analog signals of first and second frequencies are applied to excite two sets of input windings and the signal from a single output winding is split into its frequency components so as to produce error signals for driving two members to commanded positions along a common path; and an input of third frequency is superimposed upon the excitation for one set of input windings with the subsequent separation of that frequency from the output signal to monitor and confirm the operability of the inductive device and its associated components. The simultaneous control of two members may be employed without the monitoring, or the monitoring may be employed in a system controlling the position of a single member. |
