非最小相位系统的最小方差自适应控制

目标函数修正法可设计含有不稳定零点的非最小相位最小方差系统控制器,设定被控对象某时刻输入、输出、零均值、方差、平移算子,可建立其输入输出模型.定义目标函数、输出误差,若控制输入是不稳定和非收敛的,通过修正目标函数,解误差方程得出极小控制律.仿真表明修正目标函数后的最小方差控制具有较好的跟随性.

Adaptive Control of Minimum Square Error for Non-Minimum Phase System

The controller of minimum square error for non-minimum phase system contained unstable zero is designed with the correction method of objective function. Set input, output, zero mean value, square error and translation operator of controlled objects at certain time, their output models were founded. Defined objective function and output error, if control input was unstable and non-convergent, error equation was computed to educe minimum control law through correcting objective function.
