ABSTRACT:
A main feedback system regulates an output parameter of interest, such as velocity, versus a given range of load parameters, such as torque and inertia. An element feedback system rapidly adjusts an in-series-path zero to frequency track (cancel) a varying load-caused pole--including in-range variations of 100:1. Since zero-setting is inverse to an adjusted resistance required, a 100:1 zero range causes a highly non-linear resistance transmission, affecting the element loop's gain but not that of the main control feedback loop. By introducing a variable resistance of the same value as used in the main feedback system as a divider in the element feedback loop only, the element loop gain is made substantially constant over the entire pole-tracking range, and the element loop's bandwidth is made substantially constant over the same range, and thus rendering the dynamic response substantially constant over the same range. To avoid differential temperature effects on the same-value resistances, both are referenced to a common heat sink.
