In this article we'll tackle the control of multi-motors electric drives with high dynamic, rapid changes in torque and speed, rigid or flexible coupling motors, where strategy is FOC (Field Oriented Control) for each distributed local network using CANopen protocol.In surface mining industry, from which drive application selected, general trend toward asynchronous motors short-circuit rotor, due to advantages motor both terms design operation.In order achieve variable must be used static frequency converters sensorless control, speed estimated a Model References Adaptive Control Estimator.The global system proposed paper contain type MRAC estimator together PI-control based, who ensures good dynamic performance but lower complexity structure such that are properly implement real time DSP protocol software technology, as well cost flexibility use.Following these directions functional was implemented tested practice.
