8 Conclusion
Considering the consumer demand for increased efficiency and growing desires for environmental standards, designers are always looking out for new algorithms that can be used to develop low-cost, power efficient motor control systems.
The high processing power and peripheral-rich platform of a Microchip 32-bit microcontroller enable the implementation of complex algorithms on a single chip. The Sensorless FOC process uses three control loops to compensate the current and the speed. The PFC process uses two control loops to compensate the input current and output voltage. All of these compensators use a PI controller to compensate for variations in these parameters, which requires very high processing power and finer control of the system. The 32-bit microcontrollers are best suited to handle the requirements listed above because of the high resolution, good processing speed, availability of advanced analog peripherals, and the variety of instructions that support these functions.
