Sensor-less Field oriented control (FOC) of BLDC/PMSM
There are different methods of controlling a BLDC motor. Among them, Field Oriented Control (FOC) gives best performance in terms of torque ripple and efficiency. Implementation of FOC needs precise rotor position information. Sensors can be mounted on the rotor or within the motor to sense rotor position. But using a position sensor is not feasible for applications that demand high reliability or high speed or where size and cost are constraints. The reference design provides a sensor-less algorithm where a back-emf based estimator is used to estimate rotor position based on mathematical model of the motor.
Stepper motor micro-stepping
Stepper motors are used for position control and are designed to operate in open loop (without position feedback). Their inherent stepping ability allows for accurate positioning without feedback. A stepper moor can be controlled through a series of alternate pulses on stepper motor coils. But such a method will result in poor efficiency and torque ripple that generates noise. Micro-stepping along with current control is the efficient way to control stepper motor and minimize noise/vibration caused by torque ripple. Increasing the number of micro-steps improves the performance. The reference design can generate up to 2048 micro-steps and uses the principle of vector control.

BLDC with Encoder
Rotor position sensors are mandatory in applications that demand full torque at the time of starting and at low speeds. Quadrature encoder is the widely used sensor to sense rotor position with high resolution and low cost. The encoder interface algorithm in the IP converts the signals from encoder into angle and speed that can be used for FOC. The angle is incremented at each transition of the encoder signals through an interrupt. An encoder with high resolution generates interrupts at a faster rate. Implementation of encoder interface in FPGA allows parallel computation of FOC and encoder interface and doesn’t affect the FOC loop execution.

BLDC with HALL
BLDC motors are fitted with HALL sensors that provide rotor information for commutation of phases. The HALL sensors are generally used for block commutation and are not directly suitable for FOC because of their poor resolution (600 electrical). The HALL interface IP generates high resolution angle from low resolution HALL sensors. The angle and speed computed from HALL interface are used by FOC for efficient control of BLDC motor without torque ripple. As HALL sensors provide absolute position information, the motor can be operated at full torque at the time of starting and at low speeds.
