Abstract:

The tracking and stable control of a typical shipmounted mobile satellite communication system (MSCS) is studied. Unlike the former studies based on simplified single-axis models, a tri-axis nonlinear model including the kinematic and dynamic features of the MSCS is used as the control object. An adaptive robust controller with trajectory planning is designed to deal with large parametric uncertainties and uncertain nonlinearities of the system. A theoretic performance result is given and proved. The designed adaptive robust controller and other two traditional controllers are tested in the comparative simulations under three different situations. The simulation results show the tracking and stable validity of the proposed controller.
