FIGURE 8-26. FOC operation
Field Oriented Control is available on most models of Roboteq motor controllers. It uses a
classical implementation as described in the figure 8-26. The current in the motor phase is
captured, along with the rotor’s angle. From this are computed the useful Iq and wasteful
Id. Two Proportional-Integral (PI) regulators then work in parallel to control the output volt-
age amplitude and phase so that the desired Torque (Iq) and Flux (Id) currents are met. The
desired Flux current is typically set to 0 for brushless dc motors, and so the regulator will
work to totally eliminate the Flux current. The output of the PI d-q axis current controllers
yield the d-q axis reference voltage commands (Vd, Vq) applied to the motor through the
Space Vector Pulse Width Modulation (SVPWM) technique.
Both PI regulator have user-settable gains. They can be changed from the menus in the
RoborunPlus utility.

Or by sending the configuration command for single Channel Controllers:
^KPF 1 nn = Proportional Gain for Channel 1 Flux
^KPF 2 nn = Proportional Gain for Channel 1 Torque
^KIF 1 nn = Integral Gain for Channel 1 Flux
^KIF 2 nn = Integral Gain for Channel 1 Torque
