| Abstract |
The work is intended to explain the basic ideas related to design of sensorless drive with high-speed permanent magnet synchronous machine and vector control system for the oil-drowned pump. The drive and it’s control system must allow the pump operating very reliably under heavy conditions. The digital control system has a hierarchy local-distribute structure. The upper level is a ground control. The low level is a local-distribute control system, which has four drive controls. With the aim to reduce the cost of the drive and to increase reliability the sensorless pump drive is designed. Original observation algorithms of both position and rotational velocity for exterior permanent magnet synchronous motors are designed. The system simulation has confirmed high dynamic accuracy and in addition simplification of algorithm of digital control, reduction of the requirements to computing capacity of the controller |
