Motor control algorithms for Microsemi SmartFusion chips

Microsemi Corporation has made available of its new advanced motor control algorithms optimized for its SmartFusion customizable system-on-chip (cSoC) for safety-critical applications in industrial, avionics, defense and medical markets.

"Many systems require control of multiple motors which results in a dedicated micro-controller for each individual motor," said Paul Ekas, vice president of marketing for Microsemi's SoC product group. "By implementing these algorithms on SmartFusion devices that combine high-performance hardware acceleration with the easy-to-program ARM Cortex™-M3 microcontroller, designers can significantly reduce power and system complexity."

Microsemi's SmartFusion cSoC packs ARM Cortex-M3 microcontroller, FPGA and programmable analog circuitry for motor sensing.

The advanced motor control algorithms address DC brushless, AC brushless and three phase motor control applications.
The advanced motor control algorithms also include:
Field-oriented control with hall sensors
Field-oriented control with encoders
Trapezoidal commutation
Sinusoidal commutation
