fig1)Optimal Thrust Allocation
[ 研究概要 ] In the paper[1], we propose thrust allocation algorithms that handle the bases in the kernel space of a CA matrix which represents the relationship between the azimuth thrusts and control forces. The proposed algorithms satisfy the azimuth thruster angle constraints and make the real-time calculation possible in a reasonable sampling time. Numerical results are given to show the effectiveness of the proposed method, compared with the conventional Lagrange multiplier method.
