FTESO-adaptive neural network based safety control for a quadrotor UAV under multiple disturbances: algorithm and experiments
Cai, Xin; Zhu, Xiaozhou; Yao, Wen - In: Industrial Robot: the international journal of robotics … 51 (2024) 1, pp. 20-33
Purpose Quadrotors have been applied in various fields. However, because the quadrotor is subject to multiple disturbances, consisting of external disturbances, actuator faults and parameter uncertainties, it is difficult to control the unmanned aerial vehicle (UAV) to achieve high-precision...

A note on computation of pseudospectra
Janovská, Drahoslava; Janovský, Vladimír; Tanabe, Kunio - In: Mathematics and Computers in Simulation (MATCOM) 82 (2012) 10, pp. 1732-1743
The aim is to contribute to pseudospectra computation via a path following technique. Given a matrix A∈ℂn×n, we compute the branch consisting of a fixed singular value ϵ and corresponding left and right singular vectors of the parameter dependent matrix (x+iy)I−A. The fact that the...

NON-INTERIOR CONTINUATION METHOD FOR COMPLEMENTARITY PROBLEMS IN ABSENCE OF STRICT COMPLEMENTARITY
SUN, MIN; SHI, ZHEN-JUN - In: Asia-Pacific Journal of Operational Research (APJOR) 23 (2006) 01, pp. 107-122
In this paper, by using a modified smoothing function, we propose a new continuation method for complementarity problems with R0-function and P0-function in the absence of strict complementarity. At each iteration, the continuation method solves one linear system of equations and performs one...
