FOC closed loop operation Modern control drives implement the well−known Field Oriented Control (FOC) control−strategy; FOC provides efficient motor−drive for a wide range of motor−speeds, fast dynamic response, a low harmonic content of currents, and reduced losses [8−10]. In general, the implementation of FOC requires at least: • 1 Timer • 4 ADC channels (see Note below) • USART/SPI for communications • Capture/PWM FOC should achieve: • High control bandwidth • Low current distortion • Control capability at low speeds Figure 26. Graphical User Interface for Controlling the Motor in the Open Loop NOTE: One channel for the voltage level of the VSI H−Bridge, and three channels for the – three – phase currents that flow towards the motor. However, it is possible to implement the FOC strategy with only three ADC channels (two channels for current and one channel for the voltage), as we can measure two−phase currents and mathematically calculate the third one. That implementation requires one shunt−resistor less. Compact IPM, thought, comes already with three shunt−resistors. |
