摘要:

针对新能源汽车车载电子涡旋压缩机低速运行时,负载突变引起转速波动的问题,提出一种自抗扰控制(Active destabilization resistance control,ADRC)与滑模观测器(Sliding mode observer,SMO)相结合的改进低速转矩补偿控制方法。利用新型负载转矩观测器观测负载变化,将负载观测值进行转矩补偿,同时使用自抗扰控制技术设计速度控制器。在此基础上,设计一种锁相环结构趋近速度自适应变化的新型趋近律滑模观测器,并利用李雅普诺夫定理判断该新型观测器的稳定性。仿真及试验结果表明,新型负载转矩观测器能够准确地估算负载转矩。与传统低速转矩补偿控制相比,该控制方法能够实时补偿系统的扰动,使转速波动范围从4.0%降到1.6%,显著提升了涡旋压缩机低速运行时的稳定性。

Abstract:

When the new energy vehicle electronic scroll compressor runs at low speed, the speed fluctuation is caused by load mutation. A modified low speed torque compensation control method combining active destabilization resistance control(ADRC) and sliding mode observer(SMO) is presented. The load torque observer is used for tracking the load changes, the torque compensation is carried out for the load value, the ADRC is used for planning the speed adjuster. On this basis, the new approach law observer with phase locked loop free change of speed is planned, and its stableness is confirmed by Lyapunov theory. Emulation and results reveal that the new observer can track the load value accurately, compared with traditional low speed torque compensation control, the control way can compensate the destabilization of the system in real time and reduce the speed fluctuation range from 4.0% to 1.6%, and remarkably elevate the stability of the vehicle electronic scroll compressor at low speed.

Key words: Compressor, active destabilization resistance control, torque compensation, sliding mode observer, Lyapunov theory
