The presented work was directed to develop the dynamic performance of an electro-hydraulic proportional system (EHPS). A mathematical model of the EHPS is presented using electro- hydraulic proportional valve (EHPV) by Matlab-Simulink, which facilitates the simulation of the hydraulic behavior inside the main control unit. Experimental work is done and the closed loop system is designed using the linear variable displacement transducer sensor (LVDT). The controller of the system is an Arduino uno, which is considered as a processor of the system. The model is validated by the experimental system. The study also presents a real time tracking control method, based on pulse width modulation, by controlling the speed of the actuator to achieve the position tracking with minimum error and low transient time, by applying the constant input signal 50mm the transient time was 0.9 seconds and the error 1.8%.

“…Las válvulas hidráulicas proporcionales son ampliamente utilizadas en la mayoría de las aplicaciones de control de presión/flujo ya sea para uso industrial o hidráulica móvil. Normalmente se utilizan como actuadores de flujo para pistones hidráulicos en bucles de control de nivel superior, así como para controlar directamente válvulas hidráulicas más grandes que no pueden ser controladas directamente por un solenoide [1]. Se usan generalmente como sensor de posición un transformador diferencial variable lineal (LVDT) [1].…”

“…El otro tema que involucra un sistema de control de posición es la técnica de control a emplear. Las metodologías de diseño de control son varias y van desde la teoría de la retroalimentación cuantitativa, control adaptativo, modelo de control predictivo por, retroceso no lineal, deslizamiento adaptativo control de modo, control no lineal, hasta algoritmos de optimización heurística [1]. A pesar del desarrollo de una amplia gama de avanzadas estrategias de control en las últimas cuatro décadas, los controladores PID de lejos son los más utilizados en la industria.…”

The linear positioning of hydraulic cylinders is used in industrial applications, such as the positioning of flight fins on airplanes, injection molding processes, rock drilling, etc. One of the most used control techniques is the PID (Proportional Integral Derivative) control, the problem with this technique is the tuning of its three parameters. In this work, the experimental identification of the transfer function of the system to be controlled was first done, using the MATLAB toolbox ident. Then the PSO (Particle Swarm Optimization) algorithm was implemented in MATLAB codes. Like any optimization algorithm it requires a performance index or cost function, in this research ITAE (Integral Time Absolute Error) was used. The codes were tested with research papers found in the literature, polished until they were ready for any transfer function. These algorithms were then tested in the transfer function previously identified, achieving satisfactory results in the simulations. Finally, those values of the PID parameters found were tested in the linear positioning module of the Oleohydraulics and Pneumatics Laboratory at the Universidad Católica de Santa María. Also achieving satisfactory results in the performance of the controlled system: minimum establishment time, minimum rise time and minimum overshoot, which matched with the values obtained by data acquisition. Finally, the Ant Colony algorithm (ACO) was tested, looking for better results. The best results were obtained with the ant colony algorithm, for 20 ants, with 1000 nodes, and 100 tours. For the system with load the best solution was Kp = 11.01, Ki = 5.51 and Kd = 3.71. The results were improved by making a better experimental identification of the system. The solution was also improved by increasing the number of tours and the number of nodes, increasing the computational cost. With the controller implemented, the setup time was reduced from 2.5 to 0.6 seconds without overshoot and with an error of less than 2 mm.
