Abstract
Efficiency of the air motors is a function of different variables, including the head and velocity of the fluid at the inlet and outlet of the air motor, and the load on its shaft. Among these variables, angular velocity control of air motors is a challengeable area for engineering. Although servo valves seem to be promising solutions for this application, however, they are slow and expensive. As a result, they cannot properly manage the fluctuations and discontinuities of the flow as well as the disturbances in the load for the optimum efficiency. This paper has studied designing of a PWM controller for air motors by investigating different pulses with different frequencies and duty cycles. In addition, considering practical point of view, speed-measurement in rotary systems can be challengeable and sometimes impossible. These changes such as detachment and reattachment of the shaft of the system, or installing the encoder around the shaft are sometimes impossible practically Thus, this paper has also presented an indirect method of speed-measurement by using vibration signature of air motors measured by accelerometers and microphones. The experimental results indicate the capability and suitability of this indirect measurement.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
