摘要: 针对环境模拟实验室风环境模拟的阵风特性,设计开发了一种迭代学习自校正PID控制器。该控制器将设定值序列进行迭代学习优化,系统内部采用PID自校正控制策略。仿真和实验结果表明,两种控制方式的结合,可改善系统设定点改变时的动态特性,实现了对期望风环境参数的有效控制。迭代学习控制的作用下,特别是对正弦风的模拟,随着时间推移实际值可跟踪定值,保证了环境模拟的控制精度。

Abstract: According to the characteristics of gust wind environment simulation in environmental simulation laboratory, an iterative learning self tuning PID controller is designed and developed. The controller optimizes the value set points sequence by iterative learning method. The system adopts PID self-tuning control strategy. The simulation and experimental results show that, with the two kinds of control methods, which can improve the system dynamic characteristic result from set point change, the effective control of the expected environmental parameters is realized. In iterative learning control function, especially for the simulation of the sinusoidal wind, the actual value can track the set value, and the control precision of wind environment simulation is guaranteed.
