Abstract :
In this paper, an output feedback H∞ controller based on the linear matrix inequality (LMI) is adopted for control of the diesel prime mover. Diesel engines are widely used as the backup sources in power plants. However, the existence of a nonlinear, time varying dead time between the fuel injection and the production of the mechanical torque makes the speed control of the diesel prime mover a serious problem. By considering the time delay in the design procedure, the diesel prime mover with the H∞ controller can withstand large variation in the engine dead time. Computer simulations are carried out and the result is compared with that of a conventional PID controller
