A noise reduction system reduces noise associated with an input signal provided to a control system, while substantially minimizing the adverse affect on the responsiveness and stability of the control system. The noise reduction system includes a processor, a memory subsystem and processor executable code. The processor executable code causes the processor to perform a number of steps. Initially, the processor determines an input signal level of an input signal at an input of a noise reduction system. Next, the processor determines an output signal level of an output signal at an output of the noise reduction system. The processor then determines a magnitude of a difference signal which is the difference between the input signal level and the output signal level. When the magnitude of the difference signal is less than a predetermined noise limit, the input signal is provided to an input of a control system. When the magnitude of the difference signal is greater than or equal to the predetermined noise limit, the output signal is provided to the input of the control system.
