摘要
在保证自适应控制精度的前提下,找出快速收敛的参数,从而使被控系统和参考系统达到同步。针对传统的PI控制器无法获得参数波动的系统的较高的控制性能。基于模型参考自适应控制,利用PD控制器可以预料到系统误差的方向的优点,设计了一种自适应同步控制器。仿真结果表明,该自适应同步控制器能够使被控系统和参考系统达到同步,并能够较精确地控制被控系统的输出,使被控系统满足系统所要求的动态性能。这对研究组合自适应控制策略和开展多模型自适应控制器的研究提供了基础。
The fast restrained parameters of the system are found, thus making the controlled system and the model reference system achieve synchronization under the premise of ensuring adaptive control precision. Because the traditional PI - controller is unable to obtain higher control performance for the parameter fluctuating system, this paper designs a kind of self- adaptive synchronization controller based on the model reference auto - adapted controller, and using the merit of the PD - controller. The simulation result indicates that this auto - adapted synchronized controller can control the system and the reference system to achieve synchronization, and it can precisely control the output of the controlled system, thus making the controlled system satisfy the dynamic performance of the system.
