Title:
ARTIFICIAL NEURAL NETWORK-BASED POWER POSITIONING AND THRUST DISTRIBUTION APPARATUS AND METHOD
Document Type and Number:
WIPO Patent Application WO/2020/135312
Kind Code:
A1
Abstract:
An artificial neural network-based power positioning and thrust distribution method and apparatus. The method relates to a quadratic programming problem among optimization problems, and by considering the rotation angle of a front propeller and by using an artificial neural network, the method can calculate the thrust coefficient of a rear propeller in constraints of a thrust distribution problem; and then on the basis of the optimization problem of minimizing the power of the propeller by solving with a sequential quadratic programming algorithm, the method obtains a thrust distribution scheme for an all-direction propeller. By introducing the concept of a thrust coefficient, the method and apparatus precisely quantify thrust loss, and enlarge a feasible area of a rotation angle of an impeller, so that a more optimized and reasonable result is obtained for a quadratic programming problem, thereby reducing the power of the impeller and saving energy.
