摘要
综述了Anti-W indup算法的发展过程,以及大致的分类情况和各种方法的应用特点。不同角度定义的W indup现象会产生不同类型的Anti-W indup算法结构,大致可将其分为:线性结构和非线性结构算法。线性结构算法又产生两种主要类型:传统的Anti-resetW indup和条件作用。线性结构Anti-W indup算法一般符合两步法设计原则,但由于其分步设计原则,忽略了线性控制器和非线性补偿环节是同时作用在系统闭环响应中,造成了系统综合困难,即补偿后的系统性能没有明确的数学表达。针对这一问题,众多学者在线性结构算法的基础上提出了不同的设计方案,理论上取得了许多成果,可以在补偿器设计的同时得到预期的动静态性能。但是,由于事先设计的算法过于复杂,制约其在应用领域的推广,因而应用最为广泛的还是传统的Anti-resetwindup算法。如何简化事先设计算法推广其应用或改进传统的Anti-resetwindup算法直接获取最优补偿效果将是今后该领域研究的主要方向。
The development, classification and characteristics of Anti-Windup algorithms are summed up. Different identification of the windup phenomenon can produce different structure of the anti-windup algorithms. There are about two strategies ： linear-structure and nonlinear-structure algorithms of anti-windup. The former produces two types ： traditional Anti-reset windup and conditional technique. Linear-structures of anti-windup algorithm mainly belong to Two-Step design principles, but due to the principle of separating design process, the fact that both the linear controller and nonlinear compensator affect the closedloop performance is completely ignored, which results in comprehensive difficulty of system synthesis, namely the performance of system with compensator hash＇ t definitive mathematic expression. To solve this problem, numerous scholars present various schemes based on the linear-structure algorithms. The research productions in theory guarantee the expected performances of steady and transient states under design controller and compensator simultaneously. But there are some limitations in its applications because of the complexities of the prior design. By now the classical Anti-reset windup algorithm is still the most popular choice in application. How to predig tional Anti-reset windup algorithm to directly search. est prior design and extend its application or improve tradiobtain optimal compensated effect are topics of ongoing research.
