针对一类更广泛的非仿射非线性离散系统,提出一种改进的无模型自适应控制算法.该算法基于非参数动态线性化方法,运用观测器的思想,实现带有扰动系统的实时动态线性化,进而将无模型自适应控制方法的应用推广到更广泛的非仿射非线性离散系统.同时,对推广后的改进无模型自适应控制方法进行理论上的证明,并通过仿真实例验证了所提出的改进无模型自适应控制方法的可行性和有效性.
In this paper, an improved model-free adaptive control algorithm is proposed for a class of more general non-affine nonlinear discrete systems. The algorithm is based on the non-parametric dynamic linearization method and the idea of observer to realize the real-time dynamic response Linearized, and then extended the application of modelless adaptive control methods to a wider range of non-affine nonlinear discrete systems.At the same time, the improved modelless adaptive control method is theoretically proved and verified by simulation examples The proposed modelless adaptive control method is feasible and effective.
