摘要
针对一类非线性系统,利用微分几何方法中的反馈线性化方法将其等价表示为时变线性系统,再设计一个最小方差自校正调节器,利用参数估计中最成熟的递推最小二乘法对系统参数进行估计,并结合利用最小方差控制策略,实现了对原非线性系统的自适应控制.仿真表明了所提方法的有效性.
An adaptive control is implemented for a class of nonlinear system by substituting it with a time-varying linear system firstly,then differential coefficient geometry algorithm is used and recursive least-squares is used to identify the invariable coefficients.At last,minimum variance automatic correction is designed for the original nonlinear system.The effectiveness of the presented method is demonstrated by the simulation results.
