Abstract
Addressing the inherent uncertainties in the linearization of diesel engine nonlinear models and the susceptibility of conventional PID speed regulators to external perturbations, this study endeavors to enhance the control strategy through the application of robust control theory. A systematic analysis of the robust stability of the uncertain dynamical system leads to the formulation of a H∞ controller design, which is then refined through the solution of Linear Matrix Inequalities (LMI). Simulation experiments are conducted employing MATLAB/Simulink integrated with a detailed nonlinear diesel engine model. The outcomes demonstrate that the proposed robust control approach significantly outperforms traditional PID controllers in terms of its ability to accommodate modeling discrepancies and mitigate the effects of external disturbances, culminating in an improved precision in speed regulation.
