Identification and self-tuning control of electro-pneumatic actuator system with control valve

Actuator, as the execution of the terminal unit of the control system is directly related to the safe and reliable operation of the production process, and once actuators in the system malfunction, will bring huge losses. The research on pneumatic actuator not only devote to the study of its structure, but also need to study the basic theory of the actuator system modeling, and Laid a foundation for the study of the actuator fault diagnosis. Firstly, this paper introduces the components and working principle of the pneumatic actuators which mainly include three parts: pneumatic servomotor, positioner, and control valve. Secondly, the DABlib modules of MATLAB/Simulink as the simulation model of actuator failure are introduced. Finally, we analyzed the common faults of the pneumatic servomotor, positioner, and control valve, and in the MATLAB/Simulink environment, the faults are simulated, and describes the phenomenon of two typical fault.

Fire Ignition

In nowadays the pneumatic controlled systems are widely used in industrial applications where valves must be operated, where there is a fire ignition risk, or in different automation systems where a positioning action is desired. The paper presents the experimental results of a pneumatic actuator controlled by a proportional control valve. The goal of the paper is to compare the experimental results with the numerical simulation results and to improve the mathematical model associated with the experiment.
