Abstract:
1. A system for fine-tracking operator assistance in performing a control task for controlling movement of an object toward a target, said system receiving an operator input signal and a sensor derived input signal, and determining a total control input, said system comprising: a first subtractor component subtracting said operator input signal from said sensor derived input signal, to produce a combined difference input signal; a low/high filtering component for separating the combined difference input signal into a low frequency portion of the combined difference input signal and a high frequency portion of the combined difference input signal; a Low Frequency Authority Limit component applying a first gain shape to the low frequency portion of the combined difference input signal to provide a low-frequency gain output; a High Frequency Authority Limit component for applying a second gain shape to the high frequency portion of the combined difference input signal to provide a high-frequency gain output; an adder component adding the low-frequency gain output with the high-frequency gain output to form an adjusted sensor derived signal; and an output component adding the operator input signal with the adjusted sensor derived signal to form the total control input for control of movement of the object relative to the target.
