Abstract

This paper investigates the modeling and control design problem for common rail injection systems in Diesel marine engines, with a focus on $H_{infty}$ static output feedback (SOF) control. The disturbance signal is assumed to have a known frequency range, constrained within a finite frequency (FF) domain. The primary goal is to maintain the pump pressure and rail pressure at their desired reference levels by adjusting the engine speed and the injector actuation signals. To accurately capture the system's nonlinear dynamics, a model based on equilibrium points is employed. Subsequently, an SOF controller is synthesized to achieve robust pressure regulation while guaranteeing $H_{infty}$ performance, expressed as a set of linear matrix inequalities (LMIs). Numerical simulations are carried out to validate the effectiveness and robustness of the proposed control strategy.
