FOC Algorithm and Regenerative Braking in Motor Controller for Electric Vehicles

Early electric vehicles used DC motors, and the vehicle's acceleration and speed were managed by a straightforward variable resistor type controller. Because a high resistance was employed to lower the current to the motor during slow speeds, when full power was not required, a significant portion of the battery's energy was lost in this type of system as energy loss in the resistor. Only at high speeds was all of the available power utilized.

Modern motor controllers for Electric Vehicles use pulse width modulation, an electrical technique, to change acceleration and speed. The energy flow to the motor is quickly interrupted (turned on and off) by switching devices like Silicon Controlled Rectifiers. Short intervals (when the electricity is shut off) allow for high power (high speed and/or acceleration). Longer intervals lead to low power (low speed and/or acceleration).

Regenerative Braking

The majority of EV motor controllers also incorporate a regenerative braking system. When a vehicle slows down, regenerative braking is employed to use the motor as a generator to recharge the batteries. The motor controller converts some of the kinetic energy that would typically be absorbed by the brakes and converted to heat into electricity during regenerative braking, which is then used to recharge the batteries. Regenerative braking not only extends an electric car's range by 5 to 10% but also lessens brake wear and maintenance expenses.

The control strategy should be such that the motor can function over a broad speed range and create maximum torque at the lowest possible speeds for an EV powertrain to drive smoothly. We are able to precisely regulate the torque by adjusting the current since, technically speaking, the motor control must be based on torque and magnetic flux.

FOC Algorithm

An FOC-based motor control is achieved by using alternating current to energize the stator coils. Knowing the position of the rotor, which is the angle between the rotor's flux axis and the stator's magnetic axis, is essential for a motor to run smoothly.

Despite being relatively difficult to build, FOC is a math-intensive method that makes it simple to accomplish this and other goals. By breaking down three-phase sinusoidal currents into flux and torque (d-q) reference frames, the FOC algorithm is able to streamline the control of these reference frames. These two elements can each be managed independently.

Motor Control Development for Automotive Use Cases: BLDC and PMSM Motors

Electric motors that do not have physical commutators need a controller to drive them. This controller essentially switches the direction of the current in the motor windings and creates an electromagnetic flux.

As simple as it may sound, motor control development is a complicated process. The motor controller is responsible for switching the current in the winding by first determining the rotor position (Hall effect sensors, encoders, back EMF and so on). On top of that, if you have an advanced algorithm such as field-oriented control, you need to implement a number of mathematical equations in order to generate the PWM signal required to drive the motor.

Motor Control Development for BLDC and PMSM Motors

Motor control development strategy determines the performance of an electric motor. For both BLDC and PMSM motors, the control strategy is somewhat similar except for the method used for determining the initial rotor position. For AC induction motor, since there are windings on the stator, the strategy for motor control development is slightly different.

We will discuss these motor control development strategies in detail now:

BLDC Motor Control Development

BLDC motor is one of the most widely used electric motors in automobiles. It has a 3-phase stator and a permanent magnet as the rotor. A motor control solution for BLDC motor commutates the rotor by supplying DC voltage (rectangular shaped). This rotor movement induces voltage in the stator windings, called the back-EMF which is trapezoidal in shape.

It is by controlling the current in the stator, a motor controller creates the desired shape of the voltage and controls the speed and torque of the BLDC motor. Field-oriented control (FOC) is the most widely used control algorithm used in motor control development of automotive applications.

PMSM Motor Control Development

Permanent Magnet Synchronous Motor is best controlled by vector control methods such FOC. By controlling the space vectors of magnetic flux i.e. current and voltage, it becomes very easy to control a PMSM motor for varied automotive use cases.

The motor control development for a PMSM motor considers the field generating part and torque generating part separately to control the magnetic flux. An automotive grade microcontroller is required to perform such tasks as there are several mathematical transforms such as Park and Clarke transform.

The output is the 3-phase voltage generated using sinewave modulation.

Conclusion

Motors and motor control development has been the catalyst in the transition from mechanical control to automation in automobiles. The recent innovations like refinement in motor control algorithms such as FOC and regenerative braking have paved the way for automobiles which are safer, more comfortable and offer great ride quality to the consumers.
