The paper considers the problem of ship autopilot design based on Bech's model of the vessel. Since the ship model is highly nonlinear and the state vector is not completely measurable, the control system synthesis is performed by means of output feedback linearization method combined with a state observer. Due to considerable parameter variations and other substantial uncertainties a robust-adaptive...
The paper considers the problem of ship autopilot design based on Bech's model of the vessel. Since the model is highly nonlinear and some of the state vector coordinates are unavailable, the control system synthesis is performed by means of output feedback linearization method combined with a nonlinear observer.

The paper considers a problem of ship autopilot design based on the input-output feedback linearization method combined with the robust and adaptive control approaches. At first, the nonlinear ship model of Norrbin type is linearized with the use of the simple system nonlinearity cancellation. Next, as exact values of the model parameters are not known, the ensuing inaccuracies are taken as disturbances...
The paper considers the problem of ship path-following system design based on input-output feedback linearization method combined with the robust control approach. At first, the nonlinear process model is linearized by means of partial coordinate transform and a simple system nonlinearity cancellation. Since the exact values of the model parameters are not known, the ensuing inaccuracies are taken...
In the paper we consider adaptive tracking control problem of a class of partially unknown, nonlinear systems in affine form. The proposed here output feedback linearizing controller plus parameter tuning law ensure asymptotic tracking via adaptive compensation of linearly parametrized model nonlinearities. A new feature is that this controller does not require multiple differentiation of the system...
The paper is concerned with the problem of adaptive tracking system control synthesis. It is assumed that a nonlinear, feedback linearizable object dynamics (model structure) is (partially) unknown and some of its nonlinear characteristics can be approximated by a sort of functional approximators. It has been proven that proportional state feedback plus parameter adaptation are able to assure its...
