Response Surface Methodology for PD Controller Design in Tanker Ships

Applying Response Surface Methodology to PD Controller Design for Tanker Ships

Response Surface Methodology (RSM) is a statistical optimization technique used for system design improvement. In PD controller design for tanker ships, RSM enables systematic investigation of how different parameters (proportional and derivative gains) affect controller performance metrics such as overshoot, settling time, and stability. This approach facilitates finding optimal parameter combinations through structured experimental design and polynomial regression modeling. Implementation typically involves MATLAB code for generating experimental designs, simulating ship dynamics, and performing regression analysis to create response surfaces that visualize parameter-performance relationships. Key functions would include defining design variables, establishing performance criteria, and employing optimization algorithms to identify the Pareto-optimal controller settings that balance multiple performance objectives.
