用分段线性近似时变参数的自适应控制

ADAPTIVE CONTROL OF TIME-VARYING PARAMETER SYSTEMS BASED ON PIECEWISE-LINEARIZATION

用一个参数分段线性化的模型近似时变系统,得到了基于最小二乘参数估计的自适应控制。该算法计算量小,容易实现在线控制。仿真结果表明,算法具有较好的跟踪特性。

A parameter piecewise- linearization model is used to approximately fit the time-varying system. Using this model, a scheme of adaptive control based on LS algorithm is proposed in this paper. The principal advantages of the scheme are computation saving, easy implementation and fast tracking performance, which are veryfied through computer simulations.
