Motor Control Algorithms

Last modified by Microchip on 2023/11/10 11:17

Types of Motor Control Algorithms

Motor control algorithms are commonly used on Microchip MCUs and Digital Signal Controllers (DSCs).

Algorithm	Applicable Motors	Notes
Field Oriented Control (with sensor-less feedback)	Permanent Magnet Synchronous Motor (PMSM), Brushless Direct Current (BLDC), AC Induction Motor (ACIM)	High efficiency Excellent torque control Low cost
Field Oriented Control (with sensored feeback)	PMSM, BLDC	High efficiency Excellent torque control
Six-step Trapezoidal (with sensorless feedback )	PMSM, BLDC	Low Cost Good torque control at moderate and high speeds
Six-step Trapezoidal (with sensored feedback )	PMSM, BLDC	Good torque control at all speed ranges
Six-step Sinusoidal	PMSM	Low noise
Open Loop (V/F)	ACIM	Low cost
