System and method for conditioning a signal

Abstract

A method of conditioning a signal being communicated between a system to be controlled and a controller may include monitoring an actual output signal and conditioning the actual output signal. The method also includes determining the difference between the actual output signal and the condition signal and causing the actual output signal to be filtered based on the relationship between the difference between the actual output signal and the conditioned signal.

Description

TECHNICAL FIELD [0001] The present disclosure relates generally to a system and method for filtering a signal and, more particularly, to a system and method for implementing a signal conditioner that is varied based on signal posture. BACKGROUND [0002] Many control systems include multiple sensors to monitor various system parameters and thereafter communicate this system information back to the controller. Each sensor generates an output signal, which is read by the controller, in preparation for subsequent system control. However, it is often difficult to discern the true signal from the noise if the noise includes a similar frequency as compared to the true signal. One known solution includes utilizing a band pass filter to filter noise at a first frequency and thereafter allowing the true signal frequency, which is at a second differing frequency, to pass through the filter. [0003] Known filtering techniques include utilizing a band pass filter to filter out noise which may be c...

AI Technical Summary

Benefits of technology

"The patent describes a method for improving the condition of a signal sent between a control system and a device being controlled. The method involves monitoring the actual output signal, adjusting it to match a desired condition, and then filtering it based on the difference between the actual and conditioned signals. This can help to reduce errors and improve the overall quality of the signal. The technical effect of this method is to provide a more precise and reliable control over the output of a device."

Problems solved by technology

However, it is often difficult to discern the true signal from the noise if the noise includes a similar frequency as compared to the true signal.

However, band pass filters are often not acceptable since the frequency of noise may be similar to the frequency of the true signal when the signal is prone to fluctuation.

Unfortunately, if the torque output signal is similar in frequency to that of the system noise, then the filter is likely to become less effective.

In response to the need to provide aggressive response to the speed / torque signal of an electric motor, the electric motor tends to experience high frequency torque oscillations, which can result in instability and / or surging of the motor.

Moreover, high frequency oscillations may cause undesirable operational noise, reducing the useful life of the motor, and / or adversely effecting operator comfort in instances where the electric motor is utilized to animate a work machine, for example.
