Simulation and Optimization research of PMSM based on limited PI algorithms
传统的SVPWM控制算法在电机启动时容易产生转速超调和较长的稳定时间,影响系统的动态响应性能.为此,本文分析推导了SVPWM控制算法下永磁同步电机启动时的转速超调量、稳态时间的表达式,提出增大系统阻尼比可以提升系统暂态稳定性的结论.在此基础上进一步提出可以通过限幅PI算法提升系统阻尼比.通过仿真分析,验证可所提措施的有效性.
Conventioanl SVPWM control algorithms are prone to speed overshoot and prolonged setting times during motor startup,adversely affecting the system's dynamic response performance.To address this issue,this paper analyzes and derives expressions for speed overshoot and steady-state time during the startup of permanent magnet synchronous motors(PMSMs)under SVPWM control.It concludes that increasing the system damping ratio can enhance transient stability.On this basis,the paper further proposes that the system damping ratio can be improved via a amplitude-limited PI algorithm.Simulation analysis verifies the effectiveness of the proposed measures.
