High-Gain Observer-Based Sliding-Mode Dynamic Surface Control for Particleboard Glue Mixing and Dosing System

Abstract

In the process of particleboard glue mixing and dosing control under the working condition of intermediate frequency, a sliding-mode dynamic surface control strategy based on high-gain observer is proposed in this paper to deal with the problem of glue flow stability caused by strong nonlinearity. The high-gain observer (HGO) is aimed at estimating the derivative of the immeasurable system input signal for feedback, and the robustness of the system is improved by the dynamic surface control (DSC) method. Furthermore, the sliding-mode control (SMC) method is used to deal with disturbances caused by the uncertainties as well as external disturbances. It is proven that the system is exponential asymptotic stable by constructing a suitable Lyapunov function. Simulation results show that the proposed control methods can make the system track the expected flow value quickly and accurately. Finally, numerical simulation results are exhibited to authenticate and validate the effectiveness of the proposed control scheme.

Supplemental state observer‐based sliding mode control for a dynamic system

“…Extended state observer-based sliding mode control [14,15] are proposed to control the missile system and power converter system. The high-gain observer-based sliding mode control [16][17][18][19] and observer-based sliding mode control [20][21][22][23][24][25][26][27] are proposed to control the non-linear system with the unavailable states. In addition, the sliding mode observer-based sliding mode control [28,29] is proposed to estimate unavailable states for the slosh-free motion system and high voltage direct current system, respectively.…”

“…In addition, the sliding mode observer-based sliding mode control [28,29] is proposed to estimate unavailable states for the slosh-free motion system and high voltage direct current system, respectively. From the previous studies about observerbased robust controller [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29], the state observer can accurately estimate the unavailable states to be implemented in the controller.…”

“…Ayadi et al [ 43 ] implemented a high-gain observer which provides a full state estimation (position, velocity, temperatures and pressures) in an electropneumatic system. Wang et al [ 44 ] proposed a sliding-mode dynamic surface control strategy based on a high-gain observer for glue mixing and dosing control in the particleboard process.…”

Extraction and Detection of Surface Defects in Particleboards by Tracking Moving Targets

“…In recent years, many scholars have made contributions to improve the technology of particleboard production line, including those involving technical fields such as impact resistance and internal bonding strength [1][2][3][4][5][6][7][8][9]. In Reference [1], samples of high-density homogeneous particleboards of sugarcane bagasse and castor oil polyurethane resin were manufactured and subjected to low-velocity impacts using an instrumented drop weight impact tower and four different energy levels.…”
