The landing task of an aircraft under low aerodyna mic pressure on carrier requires precise airplane control. A flight/thrust integrated control system (FTICS) with constant α d, actual angle of attack, is developed using LMI based H ∞ synthesis. The typical single input/output specifications are translated into the weighting functions of an H ∞ output feedback synthesis problem. The motivation of the work is to improve the key performance of dynamic tracking and air disturbance attenuation....

The landing task of an aircraft under low aerodyna mic pressure on carrier requires precise airplane control. A flight/thrust integrated control system (FTICS) with constant α d, actual angle of attack, is developed using LMI based H ∞ synthesis. The typical single input/output specifications are translated into the weighting functions of an H ∞ output feedback synthesis problem. The motivation of the work is to improve the key performance of dynamic tracking and air disturbance attenuation. The FTICS can keep the attitude angle and the path angle unchangeable as the airplane is passing through the ramp at which the tracking radar doesnot work and the guidance signal is terminated. For engineering application, an order reduction method of the H ∞ controller is also proposed. Simulational results indicate that the system satisfies the design requirements quite well.

In order to improve the performances of the ordinary disturbance observer, this paper proposed an improved disturbance observer structure, which prossessed more parameters to be adjusted, and was the same as directly discrete design when realized in computer. Two disturbance observers were applied to a high speed high accurate table driven by linear motor. Experimental results demonstrate that the improved disturbance observer have better performances of dynamic tracking and robustness....
