摘要
针对电子助力制动系统永磁同步电机调速性能受负载影响较大的问题,提出基于扩张状态观测器的永磁电机转子动能反馈控制策略。在转子动能反馈控制策略基础上,设计了基于扩张状态观测器的负载侧功率补偿方法,解决了传统负载侧功率观测准确性与快速性矛盾的问题。通过试验验证了该方法在突然加卸负载时可使得电机动态性能良好。
In order to solve the problem that the speed control performance of permanent magnet synchronous motor(PMSM)in electronic booster system is greatly affected by the load,the rotor kinetic energy feedback control strategy of PMSM based on the extended state observer(ESO)is proposed.Based on the rotor kinetic energy feedback control strategy,a load side power compensation method based on the ESO is designed to solve the contradiction between the accuracy and the rapidity of traditional load side power observation.Experiments show that the proposed method has good dynamic performance when the load is suddenly added and unloaded.
