Through analyzing the 760mm hydraulic AGC production line of a Shandong factory, the characteristics, compositions and the mathematical model of hydraulic system of the hydraulic AGC are introduced. Based on those the system performance is analyzed on the working conditions by simulations through introducing the PID and fuzzy PID controller. The simulation analysis concluded that the system response time and overshoots with the fuzzy PID controller were better than before, which is in flavor of the production line commissioning and eventually running. The performance of AGC system affects the controlling accuracy of sheet thickness and yield of sheet directly. In order to accommodate the requirement of market and improve the competition of product, a steel plant from Shandong province entrusts relevant department to develop a set of hydraulic system, which is being debugged at present. Our paper mainly introduces the structure and feature of the system. With the mathematical model that accord with the working conditions being founded and PID and fuzzy PID based on the mathematical model being added, We have simulated the system using the software of MATLAB/SIMULINK, which supplies corresponding theoretical basis for the system’s final operation [1].

“…Similarly, a self-tuning fuzzy sliding-mode compensation-adaptive fuzzy controller is introduced for force control by a variable speed pump control system. Experimental results show that the proposed control method allows good control performance and robustness to parameter changes and external disturbances [20,21]. In order to improve the liquid level control performance of a two-axis pump-controlled folding machine, a coupled adaptive self-organizing sliding-mode fuzzy controller is constructed [22].…”

A piston piezoelectric (PZT) pump has many advantages for the use of light actuators. How to deal with the contradiction between the intermittent oil supplying and position control precision is essential when designing the controller. In order to accurately control the output of the actuator, a backstepping sliding-mode control method based on the Lyapunov function is introduced, and the controller is designed on the basis of establishing the mathematical model of the system. The simulation results show that, compared with fuzzy PID and ordinary sliding-mode control, backstepping sliding-mode control has a stronger anti-jamming ability and tracking performance, and improves the control accuracy and stability of the piezoelectric pump-controlled actuator system.

“…To solve the problem of parameter uncertainty, adaptive control (AC) was presented to estimate the unknown parameters of the EHS. [20][21][22][23] Lee et al 24 adopted an adaptive fuzzy controller for a direct pump controlled double-rod cylinder system, and results indicated that the method has a good performance in the position control of the cylinder. Guan and Pan 25 utilized the adaptive sliding control method to estimate the uncertain original control volumes of EHS.…”

This article presents a composite adaptive control method to improve the position-tracking performance of an electro-hydraulic system driven by dual constant displacement pump and dual servo motor named as a novel electro-hydraulic system with unknown disturbance. A composite adaptive controller based on backstepping method is designed to estimate the uncertainties of electro-hydraulic control system, including the damping coefficient and elastic modulus. In order to release the persistent excitation condition of conventional adaptive control, which is often infeasible in practice, a prediction error based on the online historical data is used to update the estimated parameters. Furthermore, a disturbance observer is used to estimate the disturbance including the unmeasurable load force, friction and other unmodeled disturbance. The experiment results are provided and compared with other methods to verify the effectiveness of the proposed method, and the results have indicated that the proposed method has a better position-tracking performance with the convergent estimated parameters.
