The fuzzy logic controller, which uses an analytic activation function for the defuzzification procedure, was applied to the position control of a servo pneumatic drive controlled by a proportional valve. The Gaussian shape of input fuzzy sets, with the possibility of their modification, was used to fuzzify the input signal. The control signal was determined by introducing an analytic function instead of defining the fuzzy rule base. In this way, a conventional 2-D fuzzy rule table base is modified into 1-D fuzzy defuzzification based on an analytic function to calculate the controller output. In this control algorithm, the problem of conventional fuzzy logic control, in terms of the exponential growth in rules as the number of input variables increases, is eliminated. The synthesis controller procedure is adjusted to the flow rate characteristic of the proportional valve. The developed control algorithms are verified by computer simulation and by testing on a real pneumatic rodless cylindrical drive.

“…The Equation of Motion and the Pressure Dynamics were defined based in the model suggested by [4]. Once the author adopted in his research a symmetrical cylinder, it was necessary to bring the model to the reality of the present research, where was adopted a non-symmetrical simple rod actuator that has different piston areas in the rear and front chambers.…”

This paper presents a positioning system of a linear double acting pneumatic cylinder commanded by two proportional pressure regulator valves. The advantages presented by pneumatic systems make this technology reason for constant research in the scientific field. But, the nonlinearities related to the use of compressed air and the involved frictions in the movement make the control complex. In many researches about this subject, the authors adopted proportional valves to control the air mass flow directed to the rear and front chambers of the pneumatic cylinder. In the present research, the proportional valves controlled the air pressure instead of air mass flow. The pneumatic cylinder was equipped with an internal linear resistive transducer and the proportional pressure regulator valves were set to work in double loop mode, monitoring and controlling the input and output signals of the process. Each valve was equipped with an onboard proportional integral (PI) controller which were tuned according to the second technique proposed by Ziegler-Nichols. To make possible the execution of simulations, mathematical models were developed taking into account the piston dynamics, the compressed air behavior inside the front and rear chambers, the static and dynamic frictions and the valves dynamics. To validate the mathematical model proposed, comparisons between the experimental data, collected from a prototype connected to the software Labview, and the computational simulations results, that were performed in the software Matlab / Simulink, were done. The results obtained from the experimental data returned a maximum position error of 4,48mm for positive steps inputs, which was considered satisfactory for industrial applications. The comparison between simulated and experimental responses shows that the mathematical model presents a satisfactory approximation from the real system, although the experimental results have a faster stabilization time than the simulation, the transient response and the errors were similar.

Abstract-Pneumatic driving systems are mainly used in industrial applications where the moving parts are usually fixed by the mechanical stops. For flexible and precise positioning tasks of pneumatic drives relatively expensive proportional valves have been implemented. In order to develop cheaper pneumatic servo systems, the employment of low-cost on/off solenoid valves have received considerable attention. But, the traditional technologies used in on/off solenoid valves manifest different problems caused by the electric and thermal effects, inertial forces of their mechanical parts and friction phenomenon. However, it seems that innovative technology used in fast switching solenoid valves gives better possibilities in control of pneumatic systems due to their negligible internal friction and modular architecture. In this paper a control method based on pulse-width-modulation algorithm for position control of a pneumatic actuator with high-speed solenoid valve is considered and experimentally verified.
