abstract

Controller design for marine gas turbine systems should consider three measures of performance: transient control, steady state accuracy, and distrubance rejection. This paper presents and compares two common types of controller designs in terms of these measures. The goal of the controllers was shaft speed control. To meet this goal, a classical Proportional-plus-integral controller was designed and compared to a modern Linear Quadratic Regulator design. The controllers’ performances were evaluated with respect to the three measures mentioned above, with disturbances being input as oscillations in shaft torque due to seaway cycling.
