{"title":"Trajectory Planning and High-Precision Motion Control of Excavators Based on Independent Metering Hydraulic Configuration","authors":"Junxiang Chen;Yujie Guo;Xiangdong Kong;Kelong Xu;Chao Ai","doi":"10.1109/TSMC.2025.3611946","DOIUrl":"https://doi.org/10.1109/TSMC.2025.3611946","url":null,"abstract":"This study investigates the trajectory optimization and high-precision motion control of excavators based on an independent metering hydraulic system. Considering both operational efficiency and motion smoothness, we propose a motion control method for excavator manipulators based on time-energy-jerk integrated optimal trajectory planning. The nondominated sorting genetic algorithm II (NSGA-II) algorithm is used to optimize interpolated trajectory based on five-time B-splines in the joint space. To ensure that excavators can accurately execute the planned optimal trajectory, the corresponding arms must be controlled with high precision. The oil inlet flow and the oil return pressure controllers are designed based on the independent metering hydraulic system. The flow controller is designed based on time-logarithmic barrier Lyapunov function to determine the virtual control rate and uses the Levant filter for filtering. The corresponding error transformations are employed to avoid the problem of the explosion of complexity in the traditional backstepping controller designs while ensuring that transient behavior of system tracking errors remains within specified boundaries. The uncertain components and nonlinear functions in the manipulator system are approximated by neural network (NN). Additionally, the pressure controller is used to keep the oil return pressure low to reduce system’s energy consumption. Finally, comparative simulations are conducted to verify the superiority of the proposed controller.","PeriodicalId":48915,"journal":{"name":"IEEE Transactions on Systems Man Cybernetics-Systems","volume":"55 11","pages":"8689-8700"},"PeriodicalIF":8.7,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145335256","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing models, including the classical zeroing neural dynamics (ZNDs) model and its variants, have been used to address the TDLME problem. However, those models require time-dependent matrix inversion, which is computationally demanding, and they primarily focus on measurement-related noise, overlooking other sources of system uncertainty. To overcome these challenges, we propose an inverse-free reciprocal-type ZND (RTZND) model. This model integrates an energy-based error function with the ZND framework, eliminating the need for matrix inversion and incorporating error-feedback-related noise through its closed-loop control structure. We establish the convergence and robustness of the RTZND model using Lyapunov stability theory and assess its performance under external disturbances. Numerical simulations confirm its effectiveness and improved computational efficiency in solving the TDLME problem. We further confirm its applicability through two case studies, a time-dependent linear system and a nonlinear system modeled by the single machine infinite bus (SMIB) system, highlighting the RTZND model’s practical value in addressing TDLME problems.","PeriodicalId":48915,"journal":{"name":"IEEE Transactions on Systems Man Cybernetics-Systems","volume":"55 11","pages":"8715-8728"},"PeriodicalIF":8.7,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145335279","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
