摘要
本文采用直接优化性能指标的方法,设计了离散时间的模型参考自适应控制系统,证明了最优调节器的存在性,并分别导出了确定性系统和随机系统的自适应算法.所设计的调节器参数,在一定条件下具有全局收敛性.数值模拟结果表明,所给出的算法是有效的,其控制精度和收敛性质都优于通常的自适应算法.
In this paper, we design discrete time model reference adaptive control(MEAC) schemes based on explicit criterion minimization.The existence of optimal regulators is proved and adaptive algorithms of deterministic and stochastic systems are given.The global convergence of the regulator parameters designed in this method is argued under certain conditions.The results of numerical simulation show that the given algorthms are flexible and effective, their control precision and convergence properties are superior to the usual ones.
