FIELD ORIENTED CONTROL BLDC TOOL SERIAL
Connecting over the serial interface of the MCU, it is possible to access settings in real time and even visualize information buried deep inside of the vector engine.įOC provides a significant improvement over alternative motor-control approaches, delivering lower torque ripple and better control at low rotation speeds. It provides a graphical interface to edit all motor parameters and A-VE settings. To assist in the tuning of the system, the “Motor Mind” tool can be used.

Measurements and comparison undertaken by Toshiba show that, compared to a pure software implementation, this approach delivers a 70% reduction in processor load. As such, the A-VE can read in voltage and current values from the motor phases and directly prepare the PWM for the next commutation step with very little intervention from the microprocessor.
It is also tightly coupled with the analog-to-digital converter (ADC) and pulse-width modulation (PWM) peripherals. Known as the Advanced Vector Engine (A-VE), it integrates 3-phase to 2-phase conversion, space vector modulation, along with PI (proportional/integral) control blocks that are easily configured through hardware registers.

To simplify the implementation and achieve more determinism, Toshiba has developed a series of microcontrollers (MCU) that implement the FOC algorithms in hardware. If the microprocessor is also handling other application tasks this can, in the worst case, lead to poor motor control or an unresponsive application. One significant area that causes challenges is the lack of determinism since the control algorithm can require significantly different amounts of time to execute the complex mathematics to calculate each commutation step. On top, tools are needed to garner the insights into the state of the control algorithm and allow a “look inside” to support debugging during development. This has been a challenge, both to implementers and providers of silicon solutions that use FOC, to package the hardware and the software in such a manner that it is easy to use, configure, and optimize.
