非线性自适应控制——克服非线性的影响

NONLINEAR ADAPTIVE CONTROL——ELIMINATE THE EFFECT OF NONLINEARITY

非线性自适应控制系统中，当工作点发生转移时，被控过程的增益有时会有很大的变化，这对使用广义最小方差控制的自校正控制器来说会产生一定的影响．文中对这种影响机理进行了讨论，并针对单变量系统提出两种合理的解决方法．

As the operate point changes in the nonlinear system, the gain changes much. This makes up big effect on general minimum variance self tuning control system(GMV SCS). In this paper, the mechanism is discussed, and two strategies are proposed for SISO systems.
