抗饱和比例积分控制器的建模与仿真

On the Modeling and Simulation of Anti-Windup Proportional-Integral Controller

Hantao Cui, Yichen Zhang, Federico Milano, Fangxing Li

摘要:

本文研究了IEEE标准421.5-2016推荐的具有抗饱和(AW)限制器的比例积分(PI)控制器的抖振和死锁行为。根据仿真方法的不同,控制器在某些参数和输入的组合中可能会进入抖振或死锁状态。抖动和死锁分析的上下文中的三个数值积分方法:显式分区方法(EML),基于执行列表的方法(ELM),和隐式梯形法(ITM)。本文推导了同步法和ELP法的抖振停止条件,分析了步长和收敛容限对同步法的影响。通过数值仿真验证了所推导的颤振停止条件和死锁行为。

英文摘要:

This paper investigates the chattering and deadlock behaviors of the proportional-integral (PI) controller with an anti-windup (AW) limiter recommended by the IEEE Standard 421.5-2016. Depending on the simulation method, the controller may enter a chattering or deadlock state in some combinations of parameters and inputs. Chattering and deadlock are analyzed in the context of three numerical integration approaches: explicit partitioned method (EPM), execution-list based method (ELM), and implicit trapezoidal method (ITM). This paper derives the chattering stop condition for EPM and ELP, and analyzes the impacts of step size and convergence tolerance for simultaneous method. The deduced chattering stop conditions and deadlock behavior is verified with numerical simulations.
