This paper describes an experimental study and comparison of the frequency responses of an electropneumatic positioning system with a rod and a rodless pneumatic cylinder. An experimental rig is set up to study the Bode magnitude and phase plots of an electropneumatic positioning system with different types of pneumatic cylinders, and the critical frequencies of the system are determined. A virtual instrument is used to collect experimental data. The processing and process control are automatically performed by a PC and the corresponding NI interface board. The frequency response of the system is defined by two graphs - Amplitude-frequency response (AFR) and Phase-frequency response (PFR). From the presented characteristics, the critical frequencies are determined for both systems - with double out rod and rodless cylinder. As a result of the research, it was established that in a pneumatic positioning system with a double-sided out rod cylinder, the critical frequency is higher than the system with rodless cylinder. This indicates the better dynamic properties of the system. The advantages of the rodless pneumatic cylinder are that its design occupies less embedding space compared to a cylinder with a double out rod, which requires twice the clearances for equal working strokes in industrial electropneumatic positioning systems.

“…There are several approaches have been investigated and applied to the pneumatic system such as PID controller, pole assignment controller, sliding mode controller [9][10], adaptive controller [7,11], back stepping controller [12][13], fuzzy [14][15] and neural network controller [16][17]. The tuning of the PID controller parameter have been investigated and applied to the pneumatic system.…”

Pneumatic actuator system is inexpensive, high power to weight ratio, cleanliness and ease of maintenance make it's a choice compared to hydraulic actuator and electromagnetic actuator. Nonetheless, the steady state error of the system is high due to the dead zone of the valve. In this paper, an Auto-Regressive with External Input (ARX) model structure is chosen to represent the pneumatic actuator system. The recursive least square method is used to estimate the model parameters. The poleassignment controller is then developed for position tracking. To cater the problem of high in steady state error, the dead zone compensation is added to the system. The dead zone controller was designed based on the inverse dead zone model and the dead zone compensation designed based on the desired error. The proposed method is then experimentally with varies load and compares with Nonlinear PID
