“…It is applied to the control algorithm of this motor by drawing on other control algorithms of the valve-controlled cylinder electro-hydraulic position servo system. Extensive research has been conducted to improve the performance of nonlinear controllers, such as adaptive control, 14 robust control, 15 sliding mode control (SMC), 16 and active disturbance rejection control. 17 Adaptive control can attain global progressive tracking stability, 18 but it only takes parameter uncertainty into account and ignores external disturbances having a large number of adjustment parameters.…”

The straightness control of the working face is the key technology to realize intelligent production of coal mines. However, the discontinuity of on–off hydraulic components of the existing underground working face cannot meet the needs of intelligent straightness control. A new type of dual-spool high water-based digital valve with a motor ball screw as the driving element is proposed as a solution to this problem. In this paper, the force of the valve is firstly analyzed, and it is found that the force of the movement of the valve core can be equivalent to the disturbance of the motor. The control of the valve core is essentially displacement control. In addition, a mathematical model of the valve is established, and sliding mode control with a high-gain observer is proposed to overcome time-varying characteristics of the load. Theoretical analysis indicates that the proposed controller ensures asymptotic stability with existing uncertain disturbances. Moreover, a system based on MATLAB/Simulink simulation model is developed to further verify the performance of the proposed algorithm. Compared with traditional sliding mode control and proportional integral derivative, the proposed algorithm can still improve the tracking accuracy and robustness along with 0.05 mm error under strong time-varying interference. The valve reaches the required flow in around 0.2 s, which is sufficient for the majority of work surface application situations. The research proposes a novel design concept and control approach for straightening coal mine scraper conveyors.

“…Due to factors such as the inertia of motor and pump, the distance and temperature of glue conveying pipeline, etc., it is often an uncertain system with time delay, complex disturbance and unpredictable states [5]. There are many control methods to solve this kind of system, including proportionalintegral-derivative (PID) control [6,7], active disturbance rejection control [8], sliding mode control [9][10][11], backstepping control [12], predictive control [13], neural network [14,15], etc. Sliding mode control, one of the most effective control strategies for the complex disturbance and uncertainty of the system, is widely used in motion control systems.…”

In this paper, a novel flow tracking control scheme for particleboard glue system with complex disturbance and unmeasurable system state is investigated. The method is based on hyperbolic tangent extended state observer and adaptive fuzzy fractional order global sliding mode control with exponential reaching law. The novel compound control scheme has the following advantages: Firstly, the extended state observer with hyperbolic tangent function can improve the estimation ability for the system state and complex disturbance without detailed knowledge of the controlled plant and disturbance model. Secondly, the global sliding mode control method based on fractional calculus can improve the response speed and robustness of the system, and provide a more flexible controller structure than the traditional sliding mode controller. Thirdly, the adaptive fuzzy controller is introduced to approximate the sliding mode switching term, so as to reduce the chattering phenomenon of the system. In addition, the convergence of the proposed observer and asymptotic stability of the control system are verified based on strict Lyapunov analysis. Finally, the numerical simulation results show the effectiveness of the proposed compound control scheme for particleboard glue system.
