研究弱非线性系统网络信号稳定性控制的问题。由于弱非线性系统的特性和运动模式与线性系统的特征和运动模式相差很小，造成稳定性较差。传统的稳定性控制方法通常以线性系统模型作为一阶近似，以便得到较精确的结果，但是，一旦非线性过于弱小，近似性会存在较大误差，控制结果失真。为了避免上述缺陷，提出了一种基于自适应直接逆控制算法的弱非线性控制方法。利用最小二乘插值估计算法，对弱非线性控制系统中的网络信号进行误差补偿处理，从而提高网络信号波动稳定性。利用自适应直接逆控制算法，完成弱非线性控制系统的控制。在MATLAB上仿真结果表明，利用改进算法进行弱非线性控制系统的控制，能够提高控制的稳定性，从而满足实际控制需求。

Weak nonlinear system is the characteristic and the movement mode, and linear system is slightly dif-ferent. This reason cause its poor stability, the stability of the traditional control method is usually in a linear system model as a first order approximation. In order to avoid the defects, this paper proposed an adaptive inverse control al-gorithm of weak nonlinear control method. The algorithm was estimated based on the least square interpolation, and the weak signal error compensation in the nonlinear control system processing was used to improve the signal fluctua-tion stability. Experimental results show that the algorithm can improve the stability of the control, so as to meet the demand of actual control.
