Practical L1-Based Guidance and Neural Path-Following Control for Underactuated Ships with Backlash Hysteresis

Journal of Marine Science and Engineering
The study addresses trajectory tracking control for underactuated vessels with uncertain backlash-type hysteresis. First, an improved practical L1-based guidance strategy is developed by embedding the L1 mechanism into the virtual ship framework to ...

An endochronic theory for transversely isotropic fibrous composites [PDF]

A rational methodology of modelling both nonlinear and elastic dissipative response of transversely isotropic fibrous composites is developed and illustrated with the aid of the observed response of graphite-polyimide off-axis coupons. The methodology is
