内容記述 | There exists a singularity problem in control moment gyros (CMGs). CMG singularities are classified into two types: hyperbolic and elliptic. Several gimbal steering control methods have been presented to avoid CMG singularities. Hyperbolic singularities can be avoided by null motion, but elliptic singularities cannot. The existing steering control methods are rarely designed by explicitly taking the singularity type into account. In order to effectively avoid elliptic singularities by perturbing gimbal angles, it is desirable to calculate and record the boundaries between elliptic and hyperbolic singularities in advance so that the determined boundaries can be utilized for developing model predictive steering control. To this end, the boundaries between elliptic and hyperbolic singularities of CMGs are calculated and represented in the form of fitted curves. Several numerical examples are presented to determine the perturbation gimbal angles for avoiding elliptic singularities without using singular value decomposition. |
