| Summary: | The design and optimization of hydraulic systems in marine and industrial applications are critical for enhancing operational efficiency and ensuring mechanical stability. This study explores the impact of parametric variations on the output characteristics of hydraulic systems, with a focus on pipeline parameters such as length and diameter and effects of an accumulator. Utilizing a mathematical model of an electro-hydraulic servo system, detailed analysis was conducted a to investigate the system's dynamic response to parametric changes.
The thesis utilised MATLAB to simulate the system response, analysing the effects of these variations on stability and performance through root locus plots, time response analyses, and Bode plots. Key components such as servo valves, pipes and an accumulator were incorporated into the model to ensure comprehensive coverage of the system dynamics.
Additionally, the integration of a Proportional Integral Derivative (PID) controller demonstrated significant improvements in system responsiveness and stability. By subjecting the system to step inputs and evaluating the resultant performance metrics, we observed marked enhancements in response times and reduction in oscillations, affirming the PID's efficacy in tuning complex hydraulic systems.
The findings from this study not only provide deeper insights into the design principles of hydraulic power systems in varied engineering contexts but also suggest robust methodologies for future enhancements in system design and control strategy implementation. This research contributes to the body of knowledge necessary for advancing the reliability and efficiency of fluid power systems across multiple industrial applications. |
