喷水推进动力定位推力分配方法
Thrust allocation method for waterjet dynamic positioning
摘要
Abstract
Aiming at the thrust allocation problems under complex nonlinear constraints of the waterjet model,a regional quadratic programming method was proposed.The method regarded the instantaneous reverse characteristic of the longitudinal thrust as an incomplete symmetrical change in dynamic feasible region.According to the pre-solved result and the designed sub-regional logic,a local feasible initial value and a more accurate convexity region could be obtained.Combined with the combined bias optimization solution algorithm,an optimal allocation result that meets the requirements of ship operations would be obtained.At last,a simulation verification was carried out with a research object ship equipped with waterjets.The simulation results showed that the method can effectively solve thrust allocation problems.In addition,the method has better accuracy and faster speed than traditional methods.关键词
