摘要：
This article presents a method named pseudo-inverse to solve the optimal thrust allocation of dynamic positioning (DP) system, proposes to optimally determine the azimuth angle of thrusters instead of man-control or semi-auto control, and combines with the pseudo-inverse methods to get the optimal solutions for dynamic positioning control system. It is able to greatly reduce the risk of manual mode. Three different kinds of modes are proposed and detailedly illuminated, and can be used to solve much more complex nonlinear constraint problems, such as typical forbidden vector boundary. Several illustrative examples are provided to demonstrate the effectiveness and correctness of the proposed thrust allocation modes. © 2011 Shanghai Jiaotong University and Springer-Verlag Berlin Heidelberg.
