Abstract

The present invention includes a method and system for reducing switching transients via large signal/small signal thresholding. The present invention prevents a switch from occurring if when the system (i.e., the system under control) is in small signal mode and permits switches to occur when the system is in large signal mode. Large signal and small signal modes are determined by comparing the difference between the most current value of a comparator variable and the final setpoint with a threshold distance. The system is in small signal mode if the most current value of the comparator variable less the final setpoint value is less than the threshold distance. Otherwise, the system is in large signal mode.
