A ship course controller is designed for Norrbin nonlinear ship mathematical model with matching uncertainty. Combining the backstepping algorithm with the nonlinear damping algorithm to design controller, the nonlinear damping is used to cancel the uncertainty. The integral item is introduced in the design to improve the performance of the controller. Now, general ships can only use the electric gyrocompass to measure the course angle, but they have no equipments to measure the angular velocity, so in this article another ship course controller of output feedback is designed for Norrbin nonlinear ship, firstly the angular velocity is estimated by the observer and then the ship course controller is designed.

In this paper we study the method of interpolation by radial basis functions in H~k(k ≥ 1) and give some error estimates. By means of such interpolation with a special kind of radial basis function, we construct a basis in H~k(k ≥ 1). Combined with the Galerkin method, this theory can be applied to solve boundary value problems for elliptic partial differential equations (such as the third boundary value problem for Poisson equation and the corresponding problem for the biharmonic equation), and some numerical experiments are also given.
