The Research Of Pmsm Controller With BOOST Function

Now the "haze" has become an annual keywords, In 2013 January the capital has 4 times been shrouded in haze, this month has only 5 days not haze days. Report shows, the larger city in China less than 1% air quality standards can reach the recommended WHO requirements, Global pollution top 10 cities, there are 7 in China.Based on the analysis of fuel cell powertrain, proposes a with BOOST function permanent magnet synchronous motor(PMSM) control system, get a suitable vehicle high power boost circuit topology type. This method put the fuel cell output voltage rises to stable value, contribute to optimization design of the motor, reduce stator current and improve the performance of the motor system. With the help of SIMetrix/SIMPLIS, matlab/simulink, simulate the boost circuit and permanent magnet synchronous motor control algorithm, Build and analyse parallel boost circuit small signal model.At last, the boost model with motor controller test the effective map,combining with the test bench to verify the effectiveness of the method.
