  • Improving the Pneumatic Control valve performance using a PID Controller
    Turkish Journal of Engineering and Environmental Sciences, 2014
    Co-Authors: Mohammad Heidari, Hadi Homaei
    Abstract:

    Pneumatic Control valves are still the most used in process industries due to their low cost and simplicity. This paper presents a design procedure of a PID Controller for a Pneumatic Control valve. For comparison, P and PI Controllers are also utilized for the Control valve. The bond graph method is used to model the Control valve, in order to compare the response characteristics of the valve. Simulation results are found for three Controllers of the valve. The integral time absolute error criterion is used to calculate the Controller parameters. The results show excellent closed-loop performance and the PID Controller is more robust than the P and PI Controller.

  • Quadratic optimal regulator design of a Pneumatic Control valve
    Modelling and Simulation in Engineering, 2013
    Co-Authors: Mohammad Heidari, Hadi Homaei
    Abstract:

    Pneumatic Control valves are still the most used devices in the process industries, due to their low cost and simplicity. This paper presents a regulator for Pneumatic Control valves using pole-placement method, optimal Control, full-order state observer, and minimum-order state observer and their responses will be compared with each other. Bondgraph method has been used to model the Control valve. Simulation results have been made for four models of regulator. The results show that minimum overshoot and settling time are achieved using optimal regulator of Pneumatic valve.

  • Stem Control of a sliding-stem Pneumatic Control valve using a recurrent neural network
    Advances in Artificial Neural Systems, 2013
    Co-Authors: Mohammad Heidari, Hadi Homaei
    Abstract:

    This paper presents a neural scheme for Controlling an actuator of Pneumatic Control valve system. Bondgraph method has been used to model the actuator of Control valve, in order to compare the response characteristics of valve. The proposed Controller is such that the system is always operating in a closed loop, which should lead to better performance characteristics. For comparison, minimum- and full-order observer Controllers are also utilized to Control the actuator of Pneumatic Control valve. Simulation results give superior performance of the proposed neural Control scheme.

  • Pneumatic Control of Insects in Plant Protection
    Physical Control Methods in Plant Protection, 2001
    Co-Authors: Mohamed Khelifi, Claude Laguë, Benoît Lacasse
    Abstract:

    The Pneumatic Control technique consists of using moving air to eliminate undesirable insects from crops. Pneumatic energy could be used in different modes: suction, blowing, or a combination of both. Pneumatic Control systems are often referred to as vacuums. The mode used depends on the species of insect to be Controlled and on the characteristics of the crops to be protected. The use of vacuums is limited to some crops and some insects. Hence, insects that easily fly as soon as they feel vibrations or when they are disturbed in their environment such as, the Whitefly (Aleurodidae), are best Controlled by vacuuming. The Colorado potato beetle (CPB) [Leptinotarsa decemlineata (Say)] and insects such as the European corn borer (Ostrinia nubilalis (Hbn.)) or the cabbage maggot [Delia radicum (L.)] cannot be dislodged easily by this mode. Their behavior is completely different and requires more elaborate methods. The CPB beetle holds on to the plants firmly. Furthermore, the foliage of the host potato plants becomes denser as growth advances and the generated vacuuming force rapidly dissipates. It is therefore very difficult to suck up CPBs that are deep in the plants or those that are firmly gripped to the foliage. On the other hand, the European corn borer attacks corn inside the stems. In this case, it is impossible to remove this insect by a Pneumatic system.

  • Evaluation of a four-row prototype machine for Pneumatic Control of Colorado potato beetle
    Canadian Agricultural Engineering, 1999
    Co-Authors: Claude Laguë, Mohamed Khelifi, Benoît Lacasse
    Abstract:

    Previous research work related to Pneumatic Control ofColorado potato beetle (CPB) showed that this alternate Control means is technically feasible and that it may represent an interesting alternative to chemical means. A four-row prototype machine was designed and built to implement Pneumatic Control at the field scale. Extensive testing of this machine in the field was completed during a full growing season. The effects of Pneumatic Control of CPB on the growth of potato plants and on the yields were investigated. Also, the efficiency of a specific Pneumatic strategy in ControllingCPB was evaluated. Field experiments consisted of: Control (no treatment), Pneumatic Control (once and twice per week), chemical Control, and combined chemical and Pneumatic Control (once and twice per week). Results showed that the use of the Pneumatic machine to Control the CPB did not have any negative effect on the crop development. The plots treated twice per week with the Pneumatic machine gave a comparable yield to the plots chemically treated. However, the use of the Pneumatic machine once per week resulted in very low yields. In general, variable CPB Control in the plots treated twice per week was achieved by the prototype machine. Nevertheless, the plots treated once per week were rapidly defoliated with the appearance of the large larvae (L3-L4). These results prove that the Pneumatic machine could be used to Control CPB without affecting the plant growth or yield. However, further improvements of the machine, like the shape of the blowing units, have to be considered in order to better Control CPB populations.

    Abstract:

    This paper describes the development of an augmented reality application for learning Pneumatic Control. The goal is to improve the workbook of Pneumatic Control with additional digital information. Through the implementation of the developed application, the assumption is that it will be easier for students to understand the functionality of complex Pneumatic schemes. The augmented reality application was developed for the Android platform. Students are able to download it from the Internet and use it at home, at the university or anywhere else. The application recognizes the solution of the exercise and the Pneumatic components in the workbook and covers it with additional information (for example, simulation in form of a video clip). The developed augmented reality application can be easily introduced into teaching activities in two university study courses of Pneumatic Control. Augmented reality applications, as the one described in this paper, can be a very useful tool for students during their studies, as well as for others who want to learn more about this topic.

    International Journal of Online Engineering (ijoe), 2018
    Co-Authors: Vule Reljić, Brajan Bajči, Jovan Šulc, Ivana Milenković, Dragan Šešlija, Slobodan Dudić
    Abstract:

    This paper presents an experimental setup called Pneumatic circular manipulator. The manipulator represents a modular setup that can be adapted to the new situation by simple transformations. It is used for testing various types of Pneumatic Control and energy efficiency of Pneumatic Control systems. The manipulator is primarily intended for students and their lectures. Since it has the possibility for remote Control over the Internet, due to its modularity, it can be very interesting for researchers and employees in industry. The existing version of the manipulator allows visual monitoring of the working cycle and familiarization with the basics of Pneumatic Control and motion Control for users. By future upgrade, the manipulator will become a setup that will provide feedback on the consumption of compressed air, analysis of the type of Control, cost-effectiveness analysis etc.
