The study in this paper covers torque modeling, trajectory planning and optimization control of current input of spherical actuators, in which the latter two are the major contributions. Trajectory planning is an effective way to improve the smoothness and stability of rotor motions. A novel three-dimensional (3D) orientation representation method based on manifold of S2 is proposed to facilitate...
This paper presents a novel two level current optimization algorithm for the control of the spherical motor. The proposed spherical motor consists of a rotor with 8 cylindrical permanent magnet (PM) poles and a stator with 24 air-core coils. An analytical expression of the torque model is obtained based on finite-element method. Based on this expression, the relationship between the motor torque and...
