比较了几种可模拟驱动支撑系统肩关节的三自由度半球型执行器拓扑结构。采用半解析模型来确定扭矩性能与位置的函数关系。因此，可以确定具有最小欧姆损耗的通过线圈的电流分布。执行的拓扑比较基于平均功率消耗以及一组扭矩和运动范围要求。
This paper presents a comparison of several three-degrees-of-freedom (DoFs) semispherical actuator topologies, which can mimic a shoulder joint of an actuated support system. A semianalytical model is applied to determine the torque performance as function of the position. Hence, the current distribution through the coils with minimized ohmic losses can be determined. The performed topology comparison is based on the average power dissipation and on a set of torque and range of motion requirements.
