- H02P 23/02 specially adapted for optimising the efficiency at low load
- H02P 23/03 specially adapted for very low speeds
- H02P 23/04 specially adapted for damping motor oscillations, e.g. for reducing hunting
- H02P 23/06 Controlling the motor in four quadrants
- H02P 23/08 Controlling based on slip frequency, e.g. adding slip frequency and speed proportional frequency
- H02P 23/10 Controlling by adding a DC current
- H02P 23/12 Observer control, e.g. using Luenberger observers or Kalman filters
- H02P 23/14 Estimation or adaptation of motor parameters, e.g. rotor time constant, flux, speed, current or voltage
- H02P 23/16 Controlling the angular speed of one shaft (H02P23/18 takes precedence)
- H02P 23/18 Controlling the angular speed together with angular position or phase
- H02P 23/20 Controlling the acceleration or deceleration
- H02P 23/22 Controlling the speed digitally using a reference oscillator, a speed proportional pulse rate feedback and a digital comparator
- H02P 23/24 Controlling the direction, e.g. clockwise or counterclockwise
- H02P 23/26 Power factor control [PFC]
- H02P 23/28 Controlling the motor by varying the switching frequency of switches connected to a DC supply and the motor phases
- H02P 23/30 Direct torque control [DTC] or field acceleration method [FAM]
