Aerodynamic Pressure

A high-speed centrifugal air compressor structure supported by aerodynamic pressure bearings and driven by a permanent magnet synchronous motor was proposed. The integration of air lubrication and permanent magnet synchronous motor is realized, which meets the fuel cell system's requirements for oil-free and efficient. Based on the analysis of the principle of aerodynamic pressure bearing and high-speed motor, the parameters of each component were designed, and the prototype of the air compressor was developed. When working at 10×104rpm, it can provide compressed air with a maximum pressure ratio of 2.3, and the overall efficiency is close to 80%, which achieves high-speed and stable operation, has higher efficiency and wider and flat working characteristics. Finally, the feasibility of the design was verified by bench test.

The Stability

High-speed permanent magnet synchronous motor (PMSM) is more and more widely applied in high precision processing and high-performance machines. It is very important to research practical control strategy for the stability operation of the high-speed PMSM. The strategy of sensorless grey prediction fuzzy direct torque control (DTC) is proposed which is suitable for high-speed PMSM control system. The method of prediction fuzzy control based on DTC is used to gain the flux, torque and flux oriented angle through the prediction model of the motor parameters. The best control scheme is gained by fuzzy reasoning to overcome the lag on the system making the adjustment process stable and realizing accurate predictive control. Thereby, the dynamic response of the system, anti-disturbance capability and control accuracy can be improved.
