After rendezvous and docking, the mass and mass center of target satellite can change greatly. In order to identify the mass and mass center of target satellite, research is made about the identification of mass and mass center about target satellite. As to the mass of target satellite, according to the information when the tracking satellite is located in different relatively stable position with...
After capturing the tracking satellite, the target satellite will turn into a compound satellite, and the inertia parameters of target satellite can produce great changes and greatly affect the attitude control system and its control effect. In order to estimate the inertia parameters of target satellite, two methods including the method based on Angular Momentum Conservation Law and the modified...
This paper presents a stochastic Newton method to compute the switching angles in multilevel converters so as to produce the required fundamental voltage while at the same time not generate higher order harmonics. For Newton method, a good initial guess which should be very close to exact solution patterns is necessary, so using stochastic techniques gives a new way to find possible initial values,...
This paper proposes a new principle of sensorless position estimation for a switched reluctance motor (SRM) drive, based on an improved flux/current method. The estimation algorithm makes full use of the structural symmetry of SRM, and only some specific position flux linkage data are needed, which greatly decrease the need for the high speed and capacity of microcontroller. The proposed method does...
Logistic regression algorithm and SVM algorithm are two well-known classification algorithms but when the multi-collinearity between independent variables occurs in above two algorithms, their classifying performance will always be not good. An improved classification algorithm combining the Choquet integral with respect to the lambda-measure based on gamma-support is proposed by our previous work...
