Single-Shunt Three-Phase Current Reconstruction Algorithm for Sensorless FOC of a PMSM
Daniel Torres and Jorge Zambada
A large number of motor control applications are consistently and continuously looking for methods to
improve efficiency while reducing system cost. These are the two main factors that are driving the efforts to
improve existing motor control techniques, such as trapezoidal control, scalar control and Field-Oriented Control (FOC).
FOC has become more popular in recent years due to the fact that the cost required to implement this
technique is no longer a constraint. The available technology and manufacturing process now make it
possible to implement this control technique in a 16-bit fixed-point machine such as the dsPIC Digital Signal Controller (DSC).
