Abstract This thesis addresses the optimization of control strategies within electro-hydraulic systems, aiming to achieve precise position control while minimizing energy consumption. The study delves into various control techniques (such as PID, LQR, sliding mode, MPC, NN-MPC) implemented using MATLAB and LabVIEW, evaluating their effectiveness under different load conditions. Additionally, it compares hydraulic circuits utilizing conventional proportional directional control valves (PDCVs) against those integrating flow control valves (FCVs) to assess their impact on power consumption and system efficiency. Key findings indicate that NN-MPC emerged as the most superior control strategy, exhibiting exceptional tracking accuracy and stability across varying load conditions. In contrast, MPC and sliding mode control showed limitations in terms of higher tracking errors and slower settling times compared to NN-MPC. Furthermore, integrating FCV as a hydraulic bypass into hydraulic circuits showcased significant energy savings, demonstrating approximately 15.35% reduced energy consumption at no-load and 9% at a load of 7.5 MPa compared to conventional systems lacking FCV. In conclusion, the thesis emphasizes the efficacy of employing NN-MPC for enhanced system performance in electro-hydraulic systems. Additionally, the integration of FCVs emerges as a promising approach to augment energy efficiency. The research suggests potential future avenues, including stability analysis, optimization techniques, fault detection integration, and human-machine interface development, to further advance the practical implementation and robustness of these control systems. |
