摘要
针对永磁同步电机驱动控制中逆变器升压电路结构及控制复杂的问题,本文设计了基于Z源逆变器的永磁同步电机无源性控制方案。基于能量成形和阻尼注入的无源性控制原理,构造了Z源逆变器和永磁同步电动机的欧拉-拉格朗日模型。为了克服传统永磁同步电机驱动控制系统中电压传输比有限的问题,利用Z源逆变器能够完成电压升降及逆变的功能特点,减小了电源电压波动对电机调速系统的影响,仿真结果验证了该方法的有效性。该方案实现了基于Z源逆变器的PMSM速度跟踪控制,很好地保证了该系统的稳定运行,具有良好的应用前景。
To solve the problem that structure and control of inverter boost circuit are complicated in the control of permanent magnet synchronous motor(PMSM)driving system,apassive control scheme of PMSM based on Z-source inverter is presented in this paper.The euler-lagrange(EL)model of the Z-source inverter and PMSM is established based on the passivity-based control principle with energy shaping and damping injection.In order to overcome the problem that the voltage transmission ratio is limited in the traditional PMSM drive system,the Z-source inverter drive system provides step-up voltage,step-down voltage and invert capability,therefore,the effect of power voltage fluctuation on adjustable speed servo system can be reduced.The simulation results demonstrate the effectiveness of the scheme.This scheme achieves speed tracking control of the PMSM drive system based on Z-source inverter,which ensures the steady operation of the system and has a good application prospect.
