Abstract :
It is known that DVDFB controller has salient robust stability properties independent from parameter values. It belongs to a class of static output feedback control of velocity and displacement by the collocated sensors and actuators. However, all discussions on the stability have ignored the undesirable nonlinear properties of sensors and actuators such as saturation, despite of their practical importance. Viewing this, this paper studies the robust stability by taking into account of saturations of sensors and actuators. Some simulations using flexible spacecraft are shown
