Motor Control

Sensor reduction and system operation enhancements via high-performance electric motor control algorithms.

 

High-Performance Control

Traditional electric machine control methods can leave something to be desired. By using advanced control techniques, e.g. model predictive control (MPC), performance can be enhanced: faster response, superior noise rejection, wider operation range, etc.


Reduced Current Sensor

In three-phase electric motor drives, three current sensors are typically used, with one being redundant should a sensor failure occur. We ask the question: Can this redundant sensor be removed to reduce system costs? To safely do so in case of a failure in two sensor operation, an estimator is required. Through the employment of current observers, this question can be answered in the affirmative.
