Vector control provides a fast torque response for motor control. In general, the vector control is used for the control of a rotary machine. In the case of the 3‐degree‐of‐freedom (3‐DOF) motor, the position of the rotor is changed on three‐dimensional space by tilting and rotating the motion of the shaft. Thus, when applying the vector control to the 3‐DOF motor, the 3D co‐ordinate transformation algorithm is required to decouple not only the field and torque current but the positioning (or tilting) current. The reliability of the proposed control algorithm was proven via experiments.
