摘要

针对采用固定反馈系数的传统抗饱和补偿器难以有效补偿强非线性系统的问题

提出了一种基于模糊思想的抗饱和补偿器。采用基于条件积分法和反计算法的混合补偿方式

对反计算法中所需的补偿系数进行模糊整定

在此基础上

采用硬件描述语言描述该补偿器的逻辑算法

对算法中的乘、除运算进行优化

并移植到现场可编程门阵列器件中来完成硬件的实现。实验表明

所设计的新型补偿器在直驱式转阀的控制中能够有效地提高控制精度并减少占用资源

阀芯阶跃响应的最大超调量小于3%

需要的等效逻辑门数比未优化前减少了约41%

从而证实了模糊抗饱和补偿器的可行性。

Abstract

The traditional anti-windup compensator is difficult to adapt to a strongly nonlinear systems by fixed feedback coefficients

a new anti-windup compensator from fuzzy idea is thus proposed. Conditional integral and anti-reset windup are utilized

whose feedback coefficient is fuzzily adjusted. Hardware description language is adopted to realize the algorithm

and the multiplication and division operations are optimized and implemented into the field programmable gate array to finally achieve hardware implementation for the compensator. The experiments indicate that the new compensator enables to improve the accuracy and reduce the occupancy resources significantly in the direct drive rotary valve control

the maximum overshoot of the spool step response gets less than 3%

and the needed equivalent gates decrease by 41% compared with that in usual cases.
