    ABSTRACT: We are aiming to improve the performance of a passive vibration isolator for ship-mounted antennas by designing the parameters of the isolator including nonlinear springs and dampers. It is known that a passive isolator has an inevitable problem, trade-off between minimizing the magnification of resonance and suppressing the magnifications in the region of high-frequency into lower levels. To solve this problem, we introduce a nonlinear model with more design parameters and adopt an optimization method, that is, minimizing the evaluation function consisting of two terms which indicate effects on resonant magnification and vibration isolation. By this approach, several available solutions, which can improve vibration isolation performance while with reduced magnification of resonance, are obtained.

    ABSTRACT: Recently, data traffic for satellite communications is increasing rapidly, due to various new purposes besides the conventional voice phone and facsimile. For the reason, it is necessary to realize high frequency communications, which is to be assured by high accuracy of tracking control of an antenna. To meet the needs, this paper aims at the accuracy improvement of conventional ship mounted tracking antennas by introducing H-infinity control. In this paper, the basic characteristics of tracking antenna are investigated by experiments and the model of the antenna for controller design is established. Based on the model, an H-infinity controller is designed and implemented to the antenna. Experimental results show that the tracking accuracy can be improved to ±0.3 [deg], which is five times higher than that by the conventional controller.
