“…Once the port is closed by the moving vane, the air expands to a lower pressure in a higher volume between the vane and the preceding vane, at which point the air is released via the input port 2. The difference in air pressure acting on the vane results in a torque acting on the rotor shaft [16,17]. A simplified vane motor structure is shown in Fig.…”

Wind energy has been focused as an inexhaustible and abundant energy source for electrical power generation and its penetration level has increased dramatically worldwide in recent years. However, its intermittence nature is still a universally faced challenge. As a possible solution, energy storage technology hybrid with renewable power generation process is considered as one of options in recent years. The paper aims to study and compare two feasible energy storage means-compressed air (CAES) and electrochemical energy storage (ECES) for wind power generation applications. A novel CAES structure in hybrid connection with a small power scale wind turbine is proposed. The mathematical model for the hybrid wind turbine system is developed and the simulation study of system dynamics is given. Also, a pneumatic power compensation control strategy is reported to achieve acceptable power output quality and smooth mechanical connection transition.

“…Their torque versus speed characteristics make them very well suited for many applications and they are easily reversible. There are many different designs for air motors, but two types of pneumatic motors dominate: the general vane-type air motor [1][2][3][4][5][6] and the radial piston air motor [7]. There have been a number of investigations of the dynamics of vane-type air motors.…”

“…There is large overshoot and dead-zones during the experiments. The mathematical model of a vane-type air motor non-linear system is considered a fourth-order model [4]. The parameters were identified from the experiments and the model was validated through a simulation and actual system velocity output.…”

A robust model reference backstepping (multiple-surfaces) controller is proposed for radial pneumatic motor motion systems with variable inlet pressure and mismatched uncertainties (time-varying payload). A radial pneumatic motor is first modeled by a non-autonomous equation with consideration of a ball screw table. A practical integral action and robust action are included in the backstepping design to compensate for the disturbance, mismatched uncertainty, and to eliminate the steady state error. The motion system is proved to have asymptotically stable performance and the experimental results show that the proposed controller is able to track the reference model output signal and maintain steady-state error.

“…The results of this study showed that the mode reference output could be tracked and that an accurate speed control performance was attainable. A fourth-order nonlinear mode was developed by Puan and Moore [6] utilizing parameters identified through experimental data. However, due to the complexity of this mode, the number of parameters was large, making the process of deriving parameters complicated and time consuming.…”

A robust sliding mode controller design for a ball screw table driven by an air motor

Air motors are often applied in the automation industry in areas with special requirements, such as in sparkprohibited environments, the mining industry, chemical manufacturing plants, and similar locations. The purpose of this study is to analyze the behaviors of a ball screw table powered by a vane-type air motor and to design a robust sliding mode controller for the inlet pressure. The rotational speed of the air motor is closely related to the pressure and flow rate of the compressed air. Furthermore, the compressibility of the air and the friction in the mechanism mean that the overall system is nonlinear, with fluctuating input. A robust sliding mode control is developed to overcome the effects of variations in the inlet pressure and air leakage problems. The experimental results validate the robustness of the proposed position control strategy.
