Pneumatic motors have several advantages and have many robotics and automation applications. The importance of the study is that it is a cheap and possible way to apply it to the fixed displacement pneumatic motors with simple directional control valve used. The purpose of the addition to any traditional pneumatic motors is to change the fixed displacement pneumatic motor to be variable speed and torque compared to the expensive systems such as the proportional control valve in many industrial applications. The study also included validated simulations using the Automation Studio program to control the pneumatic motor’s speed and torque. In addition, the results showed remarkable success in controlling the pneumatic motor outputs depending on the frequency of the compressed air-source pulses and pressure. The pulsating air frequencies of 1.5, 3, and 4.5 Hz were considered at different inlet source pressure changes from 1.72, 3.45, and 5.17 bar. As the pulsating flow frequency of compressed air decreased from 4.5, 3, and 1.5 Hz, the motor pressure and torque decreased. Furthermore, empirical correlations related to frequency and pressure effect have been developed. The error is 6.3–9.5% in predicting the motor speed and torque outputs. The limitation of the proposed method in real-life applications is about a maximum of 7.5 bar. On the other hand, the frequency is limited to 9 Hz using a mechanical solenoid.

Pneumatic motors have several advantages over electric motors and have many robotics and automation applications. However, the performance control of pneumatic motors is not satisfactory mainly due to air compressibility and the high cost of conventional control methods using proportional control valves. This paper presents an unprecedented application of pneumatic motor control using a pulsating compressed air technique. The study also included validated simulations using the Automation Studio program to control the pneumatic motor’s speed and torque. The results showed a clear and noticeable improvement in controlling the pneumatic motor outputs and demonstrated that the improvements are frequency functions of the compressed air source pulses and pressure. In addition, the results showed remarkable success in controlling the pneumatic motor outputs depending on the frequency of the compressed air-source pulses and pressure. Pulsating air frequencies of 1.5, 3, and 4.5 Hz were considered as inlet source pressure changed from 1.72, 3.45, and 5.17 bar. Furthermore, empirical correlations have been developed for advanced use in automatic control circuits at an error of 6.3–9.5% in predicting the motor speed and torque outputs.

The primary focus of this article is on assessing the influence of pyroeffects on the nonlinear coupled deflections of carbon nanotube (CNT) reinforced multiphase magneto‐electro‐elastic (MMEE) plates. A finite element procedure incorporating Reddy's higher order shear deformation theory (HSDT) and von Karman's nonlinear strain‐displacement relation is employed to obtain governing equations. The solutions are obtained via direct iterative method. The different volume fractions of piezoelectric and piezomagnetic phases have been considered. Also, the various forms of CNT distributions that significantly affect the coupling characteristics of the CNT‐MMEE plate have been considered. The numerical examples reveal that the pyroelectric and pyromagnetic effects play a vital role in predicting accurate structural responses. Further, this article also attempts to evaluate the effect of electro‐magnetic circuits and electro‐magnetic loads associated with the pyrocoupling, which is first of its kind. It is found from this study that the non‐dimensional deflections of CNT‐MMEE plate vary predominantly with the pyroeffects and electro‐magnetic circuits.
